OSPF asynchronous routing with two channels
Posted: Tue Jul 23, 2024 10:02 am
Hi,
There are 2 channels between the routers (GRE-tunnel).
1 router.
2 router.
When the connection is lost, a switch occurs, but when the connection is restored, router 2 switches but router 1 (ABR) does not.
I have never encountered channel reservation in OSPF before and I don’t understand why this behavior occurs.
There are 2 channels between the routers (GRE-tunnel).
1 router.
Code: Select all
/routing ospf instance

/routing ospf interface
