Hi,
I thought that I was setting up exactly the same thing, but withh the 3900
as a token-ring switch with SRB:
Both routers are running 11.2 code. The 3900 is running version 3 code.
R1 ------------------------------------------------------ 3900
------------------------------------------------------ R2
port 2 port 1
trcrf 12 trcrf 11
\trbrf 10/
ip addr 10.1.1.1
SRB
interface Tokenring 0 interface
tokenrin 0
ip addr 10.1.1.4 255.255.255.0 ip addr
10.1.1.5 255.255.255.0
multiring
all multiring all
I can ping from both R1 and R2 to 10.1.1.1 but cannot ping from R1 to R2.
I tried turning off ip routing, no effect.
I understood from reading the token ring manuals that a TrBRF would Source
Route Bridge between two groups
of TrCRFs. When I configure R1 and R2 in the same TrCRF it works fine. I
wanted to test how
SRB works in a TrBRF.
Any ideas on why this does not work? I thought that multiring all would
allow the R1 and R2 routers
to understand RIF's. But does that mean they act as end stations and send
out explorers? I see R1 or R2 sending
out arp requests out token 0 when I do the pings.
