Hi,
i have cleared already the process. "clear ip ospf p"
Currently i have only two routers and they are forming the adjacency
over a frame link.
R2 keeps winning the election and does not pay attention to the prio. I
understand
that they could not take over a DR is already elected, but in the case
when only two
are forming an adjacency...
R5
interface Serial0/0.125 multipoint
ip address 173.1.125.5 255.255.255.0
ip ospf network broadcast
ip ospf hello-interval 30
ip ospf priority 255
frame-relay interface-dlci 501
frame-relay interface-dlci 502
no frame-relay inverse-arp IP 503
no frame-relay inverse-arp IP 513
end
R2
interface Serial0/0
ip address 173.1.125.2 255.255.255.0
encapsulation frame-relay
frame-relay map ip 173.1.125.1 205
frame-relay map ip 173.1.125.5 205 broadcast
no frame-relay inverse-arp
frame-relay lmi-type cisco
end
