[j-nsp] Next-Hop Verification for static route WITHOUT BFD

[Alexander Marhold]

Hi !

 

In the old Junoe E router we could use RTR to verify a next-hop for a static
route when the neighbor is not able or willing to do BFD

 

host1(config)#ip route 10.1.1.5 255.255.255.0 10.1.1.5 fastEthernet 1/0
verify rtr 5 last-resort

 

I do not find any good example of doing this on a MX.

 

I need such a solution to change the BGP next-hop on an interface when the
interface is always up, but the necessary next-hop on this multipoint
interface is not reachable

 

The successor of RTR namely ip-monitoring is not able to this in a simple
way.

Maybe any special policy or event-policy or an event-script can help here?

Or a unknown way to redistribute the static route to OSPF only when the
next-hop is reachable vis ip monitoring ?

 

So if you have a practical way to do this please tell.

To clarify it is not a matter of milliseconds, it is a matter of seconds 

 

What I want to achieve is that when the next-hop of this static route is not
reachable, the static route is not readvertised into OSPF anymore and a
second MX then looses the primary BGP next-hop and can then divert the BGP
traffic to secondary Peer and next-hop.

 

Many thanks in advance for your ideas and solutions
