Anyone have any problems running virtual-links with PPPoFrame?
 
I ran into a problem trying to help a client the other day that required me to change the OSPF cost of the virtual-template to resolve the reachability issue (metric was >65535)... strange cause I thought 65535 was the max for OSPF. I saw it was 65610 and then the router with that metric didn't advertise the route.
 
 
R1 ---- ethernet ------ R2 ----- PPPoFrame ----- R3 ------ethernet ------ R4
 
R1-R2 link area 0, R2 to R3 link Area 10, R3 to R4 link area 20.
 
Virtual link R2 to R3. Look at R2 metric for R4 ethernet is > 65535 (its like 65610) Of course R1 doesn't see R4 ethernet.
 
I thought that was strange cause I dont recall ever having to change the ospf cost for the virtual-template interface.
 
Any ideas or just some circumstantial stuff....?
 
Andy
