How to upgrade the software (Ios) in a router with vrfs configuration?
01-03-2006 02:14 AM
Hi,
the safest way would be through the global routing table through TFTP. In this case IOS upgrade is not different to a router without VRFs configured.
Hope this helps

P.S.: in case you have a more specific problem, please provide more information.

Hi Martin,
My problem is that I don't have any entries in the global configuration.
In fact, I have 2 separate vrfs routing table and the router use the global routing table to access the tftp server.
I have a workaround with a tftp server in the lan and if I remove the ip vrf forwarding in the ethernet interface, I suppose that it' work because in thic case , I have a directed connected in the global command.
Do you have another solution ?
Thanks,
Regards,
José

Hi,
there is the possibility to create VLAN subinterfaces and place one VLAN in global routing context - actually any subinterface would do.
You also ahve the problem of SNMP access and other things not yet being fully VRF aware. So for management purposes it´s still a good practice to have global routing access to routers with VRFs.
Hope this helps

Hi,
For snmp, I have a loopback configured in a vrf and then I don't have a problem for management.
I can't configured vlan and also I used vrf lite for address-family in BGP
It's important to know that in global routing table, I receive any update because BGP vrf lite.
Question: It' possible that the upgrade use a vrf routing table and NOT global routing table?

Hi,
in fact it should be possible with the help of
ip tftp source-interface
or
ip ftp source-interface
specifying an interface in the VRF, where the TFTP server is to be found.
Hope this helps

Hello Martin,
I have also try with the command ip tftp source-interface last week but without success.
I will try with the workaround that I have proposed and the customer is agree.
Thanks very much for your collaboration, it was a pleasure to work with you.
Happy new year !!!!
