I`m trying to modify nex-hop address when redistributing from BGP to ISIS.

My problem is that I have å router doing redistribution from BGP to ISIS but I don`t want traffic going to that router.

Has anyone done this?

I havent tried this, but you should be able to this by using a route-map in the redistribution statement.

Simply put an entry in the route-map to change the next hop,


route-map bgp2isis permit 10

set ip next-hop x.x.x.x

Give it a shot and see if it works...

I tried that with the following configuration:

Router ISIS

redistribute bgp 65010 metric 15000 route-map BGP-2-ISIS

ip access-list standard BGP-2-ISIS-ACL

permit log

deny any log

route-map BGP-2-ISIS permit 10

match ip address BGP-2-ISIS-ACL

set ip next-hop

The set ip next-hop is a policy route command you want just set next-hop

Not real sure this is going to work. Normally when you redistribute a into a routing protocol you are saying I know how to get to this network so come to me. I use ISIS so little I forget if it keeps a next-hop field in his database.
