NimbostratusOSPF redistribute kernel uses 127.1.1.1 forward address
Hi All,
We are trying to advertise a virtual address into OSPF using the following imish config
router ospf 24
auto-cost reference-bandwidth 40000
bfd all-interfaces
redistribute kernel metri...
Just out of curiosity have you tried apply a route-map to filter outbound advertisements so that only the intended self/floating IP's are advertised? Not sure where the 127 address is coming from without seeing your entire config but this would be a quick way to prevent it from being advertised.
Hi Paedrig, correct - you wouldn't necessarily need to set the next-hop however, simply filtering the outbound advertisement should work as intended. You can use both next-hop and the outbound filter in combination for the desired effect. Also, I would suggest as a best practice to filter inbound out the adjacent router, this would prevent any error advertisements in both directions.
Something like this should do the trick:
redistribute kernel route-map virtual-addresses-out
access-list virtual-addresses permit x.x.x.x/xx
route-map virtual-addresses-out permit 10 match ip address virtual-addresses
If you want to upload you config to iHealth and/or open a case I'd be happy to take a look at your config.
