Asunto: OSPF virtual-link down due to "max-metric" command
Hi,
I noticed this problem is because of doing IEWB Vol2 Lab4.
In task 4.5, we need "max-metric router-lsa" to prefer R2 as the transit
router.
But if I put this command, the virutl-link between R1-R3 will get down.
Strange anyone noticed about this?
Rack5R1(config-router)#do sio vi
Virtual Link OSPF_VL0 to router 150.5.3.3 is up
Run as demand circuit
DoNotAge LSA allowed.

Rack5R1(config-router)#do srr ospf
router ospf 1
router-id 150.5.1.1
max-metric router-lsa
As soon as I put the max-metric command on R1, R3 will take the virtual-link
down

Anyone had experience of this?
