how to configure the ISIS ROUTER ID?

StarOfWest · Created Aug 8, 2018 09:51:28

ISIS work at OSI level, so there is no router ID :).
Similar to router ID, ISIS defines system ID (part of NET). Here there is a short snip with the commands required to configure system ID.
# Set the NET to 10.0001.1010.1020.1030.00, in which the system ID is 1010.1020.1030 and the area ID is 10.0001.
<HUAWEI> system-view
[HUAWEI] isis 1
[HUAWEI-isis-1] network-entity 10.0001.1010.1020.1030.00

ISIS Level-1 Traffic Engineering Status : Configured
ISIS Level-2 Traffic Engineering Status : Configured
ISIS Router ID : 0.0.0.0

Tell me what it means - ISIS Router ID ?
And why is he - 0.0.0.0 ?

In MPLS TE, it's a little bit different. It must refer to Traffic Engineering router ID which is stored in the ISIS TLV.

Try the following command sequence to see whether it changes.

<HUAWEI> system-view
[HUAWEI] mpls lsr-id 1.1.1.1

Be careful to not run this in production environment, it may restart your LDP sessions. This post was last edited by StarOfWest at 2018-08-09 09:27.

Colleague is all about what you say is set up :

mpls lsr-id 192.168.192.1
mpls

Interested in the meaning :

ISIS Router ID : 0.0.0.0

Tell me what it means - ISIS Router ID ?

Friend, please check below my reply to your queries:

1. Tell me what it means - ISIS Router ID ?
- it represents the MPLS LSR ID and it's registered into Traffic Engineer router ID TLV. Huawei should not call it ISIS router ID, this is my honest opinion, because it may become confusing.
2. And why is he - 0.0.0.0 ?
It's 0.0.0.0 because you didn't configure MPLS TE. As I said previously ISIS doesn't have a router ID.
Once you enable MPLS TE the MPLS LSR ID will change from 0.0.0.0 to 1.1.1.9 for example.

Check the proof:
