Source-bridged traffic over Frame Relay Problem

Source-bridged traffic over Frame Relay Problem

Post by Kim Hans » Sat, 19 Aug 1995 04:00:00



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!
