1. Introduction to RBFS IS-IS

The RtBrick Full Stack (RBFS) is a distributed, web-scale network operating system based on micro-service architecture and packaged in a Linux container currently based on Ubuntu 18.04. The RBFS decreases the complexity of a network by providing users with capabilities such as composability, programmability, and elasticity in a visionary way.

The RBFS operating system operates on the leaf and spine framework. This framework provides the network operators with methods to configure and manage a network brick by brick, and provides full control of the network so the focus can be on the deployment of the new services and not the constant juggling of hardware. The Intermediate System-to-Intermediate System (IS-IS) protocol is an interior gateway protocol (IGP) that uses link-state information to make routing decisions.

1.1. IS-IS Overview

IS-IS, or Intermediate System to Intermediate System, is an open standard routing protocol. ISO published the standard as a way to route datagrams as part of their OSI stack. IETF later republished the standard, and added IP route support.

It is a link-state routing protocol, similar to OSPF. It forms neighbor adjacencies, has areas, exchanges link-state packets, builds a link-state database and runs the Dijkstra SPF algorithm to find the best path to each destination, which is installed in the routing table.

This guide provides the various IS-IS configuration and show CLI commands for RBFS.

2. Configuring IS-IS

The basic IS-IS configuration tasks that must be performed are:

  • enable IS-IS protocol

  • configure IS-IS Instance

    • configure system ID

    • configure area addresses

    • configure instance level

  • configure interfaces

  • configure address-family

2.1. Entering configuration mode

The following example shows how to enter the configuration mode.

root@rtbrick:~$ cli
root@rtbrick: op> switch-mode config
Activating syntax mode : cfg [config]
root@rtbrick: cfg>

From this prompt, you can enter the set commands to configure the various IS-IS components.

2.2. Enabling IS-IS Protocol

To enable IS-IS, you must configure the ISIS protocol under a specific instance.

set instance <instance> protocol isis

instance

Name of the IS-IS instance

Example
root@rtbrick: cfg> set instance ip2vrf protocol isis
root@rtbrick: cfg> commit

2.3. Configuring an IS-IS Instance

After enabling IS-IS, the following parameters can be configured in an instance.

2.3.1. Configure the System ID

A system ID uniquely identifies a device.

set instance <instance> protocol isis system-id <system_id>

instance

Name of the IS-IS instance

system_id

specifies the system ID of the device.

Example
root@rtbrick: cfg> set instance ip2vrf protocol isis system-id 1920.0100.4001
root@rtbrick: cfg> commit

2.3.2. Configuring the ISO Area Addresses

set instance <instance> protocol isis area <area>

instance

Name of the IS-IS instance

area

The area can be represented in 1, 3, 5, 13 bytes format.

Example
root@rtbrick: cfg> set instance ip2vrf protocol isis area 49.000/24
root@rtbrick: cfg> commit

2.3.3. Configuring the Holding Time

set instance <instance> protocol isis holding-time <holding_time>

instance

Name of the IS-IS instance

holding-time

Specifies how long a neighbor should consider this routing device to be operative without receiving another hello packet.

Default value: 30 seconds

Range: 1 through 65535 seconds

Example
root@rtbrick: cfg> set instance ip2vrf protocol isis holding-time 45
root@rtbrick: cfg> commit

2.3.4. Configuring the Router ID

This command allows add a 'router-id' configuration option to IS-IS and advertise the configured router id in TLV 132 (IP Interface Address) and TLV 134 (TE Router ID)as part of the LSP.

Syntax

set instance <instance-name> protocol isis router-id <router-id>

Command arguments

<instance-name>

Name of the instance

<router-id>

Router identifier

Example
supervisor@isis_ler1: cfg> set instance service protocol isis router-id 19.10.11.14
supervisor@isis_ler1: cfg> commit

2.3.5. Configuring the SRGB Base

set instance <instance> protocol isis srgb-base <srgb_base>

instance

Name of the IS-IS instance

srgb_base

set instance <instance> protocol isis authentication level-1 type <level1_authentication_type>

instance

Name of the IS-IS instance

level1_authentication_type

Enables you to specify the authentication scheme for IS-IS. If you enable authentication, you must specify a password by including the authentication-key statement.

The following authentication types are supported:

  • clear_text

  • md5

  • sha1

Example

2.3.12. Ignoring the attached bit on IS-IS

This configuration allows you to enable the routing device to ignore the attached bit on incoming Level 1 link-state PDUs. If the attached bit is ignored, no default route, which points to the routing device which has set the attached bit, is installed.

Syntax

set instance <instance-name> protocol isis ignore-attached-bit <true | false>

Command arguments

<instance-name>

Name of the instance

<true/false>

Specifies whether ignore-attached-bit configuration is enabled or not

Example
admin@rtbrick: cfg> set instance <instance-name> protocol isis ignore-attached-bit true
admin@rtbrick: cfg> commit

2.3.13. Configuring no-mpls-transit-route

This configuration allows you to prevent IS-IS from installing the transit path for the received Segment Index for IS-IS segment routing. This configuraton should be used only if the router is an edge node which is neither expected to act as "router on a stick" or as a transit node in any topology change.

Syntax

set instance <instance-name> protocol isis no-mpls-transit-path <true|false>

<instance-name>

Name of the instance

<true/false>

Specifies whether no-mpls-transit-route configuration is enabled or not

Example
supervisor@isis_ler1: cfg> set instance <instance-name> protocol isis no-mpls-transit-path true
supervisor@isis_ler1: cfg> commit

2.3.14. Disabling IP version 6 (IPv6) routing

By default, RBFS supports both IPv4 and IPv6 routing. When IS-IS is used only for IPv4, you can disable the IPv6 routing so that RBFS does not send IPv6 data.

Syntax

set instance <instance-name> protocol isis ipv6-disable <true | false>

<instance-name>

Name of the instance

<true/false>

Specifies whether the ipv6-disable configuration is enabled or not. When you set this value to "true", it indicates that IPv6 configuration is disabled.

Example
supervisor@isis_ler1: cfg> set instance default protocol isis ipv6-disable true
supervisor@isis_ler1: cfg> commit

The example below shows the configuration after ipv6-disable is performed.

3. Configuring IS-IS Interface

By default, there are no interfaces associated with IS-IS.You must configure at least one IS-IS interface for ISIS adjacency formation.

After enabling IS-IS, you need to specify on which interface IS-IS will be run with the following command:

set instance <instance> protocol isis interface <interface>

instance

Name of the IS-IS instance

interface

Name of the interface

Example
root@rtbrick: cfg> set instance ip2vrf protocol isis interface memif-1/2/1/0

interface_type

The interface_type specifies the interface type. NOTE: The point-to-point is the default interface type and hence you actually do not need to configure it.

Example
root@rtbrick: cfg> set instance ip2vrf protocol isis interface memif-1/2/1/0 type point-to-point
root@rtbrick: cfg> commit

3.2. Configuring the Interface Adjacency

set instance <instance> protocol isis interface <interface> level-1 adjacency-disable <level1_disable>

set instance <instance> protocol isis interface <interface> level-2 adjacency-disable <level2_disable>

These commands allow you to disable level-1/level-2 adjacencies on an interface.

instance

Name of the IS-IS instance

interface

Name of the IS-IS interface

level1_disable level2_disable

These parameters allow you to enable to disable the level-1/level-2 interface adjacency

Example
root@rtbrick: cfg> set instance ip2vrf protocol isis interface memif-1/2/1/0 level-1 adjacency-disable true
