Source-Bridge over Frame Relay Problem (SOLVED!!!)

Source-Bridge over Frame Relay Problem (SOLVED!!!)

Post by Kim Hans » Wed, 06 Sep 1995 04:00:00



Hi All!

Just an update on the source-bridge frame-relay problem I posted
here previously.  The problem finally appeared in a MUX that was
not correctly optioned for B8ZS.  This was discoverd after sending
an extended ping of 0x000 bit pattern down the FR pipe.

Thanks to everyone that replied and helped, especially Tom
Sherek at ACS for pursuing this matter after the last month.

Thanks again!

Kim

1. Source-bridging problem over frame-relay

We are having a problem with source-bridged traffic over a
T1 frame-relay link.  We have a Cisco 7000 router running
point-to-point subinterfaces going to a Cisco 2502 router.
All IP traffic flows just fine, but we are unable to get
a source-bridged traffic to flow over the links.

Here is the configuration for the 7000:

! Remote Peers to Loopbacks on other routers
!
!
source-bridge ring-group 4095
source-bridge remote-peer 4095 tcp 164.154.64.129
source-bridge remote-peer 4095 tcp 164.154.240.1 (Loopback on 7000)
source-bridge remote-peer 4095 tcp 164.154.16.129
source-bridge remote-peer 4095 tcp 164.154.8.129
source-bridge remote-peer 4095 tcp 164.154.80.129
source-bridge remote-peer 4095 tcp 164.154.48.129
source-bridge remote-peer 4095 tcp 164.154.112.129
!
interface Serial2/6
description Circui ID 51-UHDA-94861 to Frame Relay (Sioux Falls)
no ip address
encapsulation frame-relay
!
interface Serial2/6.17 point-to-point
description DLCI 17 Frame Relay connection to Sioux Falls REV
ip address 164.154.200.129 255.255.255.128
frame-relay interface-dlci 17 broadcast
!

Here is the configuration for the 2502:
!
! Remote Peers to Loopbacks on other routers
! Connected on the Cisco 7000 via leased lines
!
source-bridge ring-group 4095
source-bridge remote-peer 4095 tcp 164.154.64.129 (Loopback on 2502)
source-bridge remote-peer 4095 tcp 164.154.240.1
source-bridge remote-peer 4095 tcp 164.154.16.129
source-bridge remote-peer 4095 tcp 164.154.8.129
source-bridge remote-peer 4095 tcp 164.154.80.129
source-bridge remote-peer 4095 tcp 164.154.48.129
source-bridge remote-peer 4095 tcp 164.154.112.129
!
interface Serial0
description Circuit ID 51-UHDA-94764 T1 Frame Relay to Pierre
ip address 164.154.200.130 255.255.255.128
encapsulation frame-relay
ip split-horizon
frame-relay map ip 164.154.200.129 16 broadcast

Is this configured correctly for source-bridge traffic?
If so, are there any framing issues over T1 that should
be taken into consideration?  BTW, the connection between
the 7000 and 2502 works fine over a leased 56K line.

We've been working on this one for over a month, and
would GREATLY appreciate any help in this problem
Thanks in advance!
