policy routing questions

[lcd_shouldit]

route-map TEST

match ip address TEST

set ip next-hop verify-availability 10.16.98.253 1 track 1

set ip default next-hop 12.12.12.2

Is the next-hop 10.16.98.253 MUST BE a directly connect next hop ？？？

I want to use a loopback address , Cause there are two links between the routers , I tried , but I found this does not work.......

Hi,

yes it has to be connected but if your IOS version supports you can use a non directly connected next-hop with the  set ip next-hop recursive feature.

thank you very much!!!

Can I also use verify-availability and track , I checked this set ip next-hop recursive command , but it does not have

verify-availability and track options

Cause what i want to track the link is not a directly connected link.

I configurated the policy routing on R4, which make the traffic from R5 first next hop is R3`s Loopback , then get to R7.

I also configurated IP SLA and Track, which monitor the link between R3 and R7, if this link is down, then i set a default next hop,

make the traffic from R5 to  the next hop directly to R7.

Hi,

set the recursive next-hop as R3_R7 serial IP of R3, install 2 static routes to this IP address on R4 pointing towards R3( this way you'll load balance on both ethernet links on R4-R3). configure tracking on these static routes and you'll achieve your goal.
