Title: OSPF Trivia
You can talk to from spoke to hub but what maps the other spokes IP
address to the DLCI on the spoke that I am on. Inverse arp maps the
ip of the hub to the DLCI so I can send that packet but since the
other spoke is on the same IP subnet, ip routing will try and send it
out my frame interface. I do not have a DLCI to IP mapping to make
that packet and I would get a encap failed. The problem that I
presented was that one of the spokes were elected as the DR and the
other spoke could not talk to the other spoke. I would have to either
make the hub the DR or put in additional frame map commands on the
spokes to map the other spokes IP address to the DLCI.
Hub Router (10.1.1.1) - inverse arp resolved the following
10.1.1.2 102- spoke B
10.1.1.3 103- spoke C
Spoke B (10.1.1.2) - inverse arp resolved the following
10.1.1.1 202 - Hub Router
Spoke C (10.1.1.13) - inverse arp resolved the following
10.1.1.1 203 - Hub router
If Spoke C was the DR then how can Spoke B talk to Spoke C? The only
way that I know if the put "frame map ip 10.1.1.2 102" on Spoke B and
the reverse of Spoke C.
Thanks,
