Removing OSPF routerid on VR-Default

galimuna — Wed, 21 Oct 2020 12:45:55 GMT

Hi,

I have a X460-G2 Switch which has 2 VRs configured on it and by mistake I configured a routerid on the VR-Default. Now, I am trying to remove the routerid from the VR-Default and leave only the VR-Production where it should be (this is the only VR that does OSPF on the Switch) and I couldn’t find anything until now. Does anyone had a similar issue? or does anyone have an idea how I could remove the routerid?

thanks in advance

galimuna,

It is no clear what you’ve done/ask.

Can you share the output of “show conf ospf”?

Hi Miguel-Angel

the issue is this, I have on one Switch 2 VRs, one is VR-Default and VR-Production. On VR-Default is only L2 Switching but on VR-Production I have L3 and OSPF. By mistake I configured the routerid on VR-Default and VR-Production. I need to delete the routerid from the VR-Default configuration.

This Switch has an ISC with another switch which has only on VR-Production the routerid.

This is my configuration:

# Module ospf configuration.
#
configure ospf routerid 10.174.68.90
configure ospf vlan ISC priority 0
configure ospf vlan ISC_HELPER priority 0

#
# Module ospf configuration on virtual router VR-Production.
#
virtual-router VR-Production
configure ospf routerid 10.174.68.90
enable ospf
create ospf area 0.0.0.3

….

Thanks for the replay

This is the config of the other Switch:

#
# Module ospf configuration.
#
configure ospf vlan ISC priority 0
configure ospf vlan ISC_HELPER priority 0

#
# Module ospf configuration on virtual router VR-Production.
#
virtual-router VR-Production
configure ospf routerid 10.174.68.91
enable ospf
create ospf area 0.0.0.3

galimuna,

If there is only L2 on the VR-Default, there is no impact.

You didn’t enabled ospf on the VR-Default.

You can set the routerid to another value (1.1.1.1 for example).

I didn’t checked the commands to remove the routerid.

It should be something like unconfigure, delete or disable

Hi Mig,

I thought the same and just tested it. There is no unconfigure, delete or disable command to clear the router ID. Now I’m also a bit confused. 😄

Best regards
Stefan

Galimuna, Stephan,

The default behaviour of the EXOS is to use an automatic routerid asignement, so put it back as such with configure ospf routerid automatic

Example on GNS3:

* EXOS-VM.6 # configure ospf routerid 10.174.68.90

* EXOS-VM.7 # show conf ospf

#

# Module ospf configuration.

#

configure ospf routerid 10.174.68.90

* EXOS-VM.8 # configure ospf routerid automatic

* EXOS-VM.9 # show conf ospf

#

# Module ospf configuration.

#

* EXOS-VM.10 #

Let me know,

Mig
