Hi,
using a 7604 router in MPLS environment with IOS 2.3 SR2A
10 VRF defined. Yesterday whe make a change in production to send a static route to null0 for a temporary time.
After the test, whe changed the static route pointing to null0 to the original route
ex :
Before the change
ip route vrf PROD 10.6.0.0 255.255.0.0 10.6.124.30
Everything works fine
Change :
ip route vrf PROD 10.6.0.0 255.255.0.0 Null0
We make this change to forbid access to 10.6.0.0 subnet
Everything works fine
Come back :
ip route vrf PROD 10.6.0.0 255.255.0.0 10.6.124.30
After this, the router goes down in rounting. Some subnet directly connected disapear, are not redistributed ...
We have to reload the router to work properly.
Any idea ????
Best regards
