ospf p2p network type vs frame relay inarp [7:63579]

2003-02-23 Thread Paul Dong So
Hi all,
I did some tests and found this problem.
Ra is the hub of fr connection, rc is the spoke

When only inarp used, all ospf network types passed the test except p2p
network type. No adjacency was able to be established. OSPF states kept
looping between init, exstart and exchange. Note, same configuration, only
"ip ospf network" statement was changed.

I could not find any document about ospf p2p type vs frame relay inarp.
Does anyone else come across the same problem in the lab?

Thanks

Paul

Hi,

the reason is that the serial interface with encapsulation
frame-relay is a point-to-multipoint interface by default.
Inverse ARP allows multiple DLCIs.

If you want to use point-to-point links, you have to use a ptp
subinterface. But then you cannot use inverse arp (it only works
on the main interface). You have to specify the DLCI.

Example:
interface serial 0
 no ip address
 encapsulation frame-relay
interface serial 0.1 point
 ip address xxx
 frame-relay interface-dlci xx
end
