Hi All,
I'm just trying to get a handle on ISIS over frame relay. It =
would seem that because there's no comparable command to the "ip ospf =
network" under ISIS that this limits the configuration options over =
frame-relay. It's noted that cisco serial interface with frame-relay =
encapsulation defaults to a multi-point interface. For some reason I =
can't get ISIS neighbor adjacencies being formed using a full mesh =
frame-relay cloud.=20
I'm using the configuration example in Doyle's Routing TCP/IP, pg. 652. =
I replaced the ethernet segment between the L2 devices(London, Rome, and =
Brussels) with frame-relay. In my frame-relay configurations I'm able =
to ping all points of the cloud but I'm unable to get adjacencies to =
form. All routers are configured with physical interface(multi-point, =
being the default) but I still get encapsulation failure when observing =
the "debug isis adj-packets". Now I've got this to work when the =
devices are configured using point-to-point sub-interfaces in a partial =
mesh(hub and spoke topology) and the hub configured for individual =
p-t-p's for each pvc.
I am however trying to simulate the ethernet segment I'm replacing.. I'm =
I thinking way "out the box" here or is this possible"
For reference there's a basic example on pg. 678 of Doyle's book that =
covers the frame-relay issue I'm trying to resolve...
Thanks All,
Nigel.
