I am working on an TokenRing to Ethernet Migration. Because one of the subnets used in the TokenRing environment is a subnet filled with DNS, NTP and other quite important server, I would like to use that subnet again in the ethernet environment. Therefor I was building a temp. translational bridge using a 2612 which was on my desk for testingpurposes. I do not have a 3600 of more heavy router.
Using the website of Cisco I have configured the translational bridging. Turned off IP routing, created a virtual ring, ringgroup etc. Broadcasts send over tokenring are received on ethernet. But packets send from ethernet to tokenring are never seen on the TokenRing segment using a network sniffer.
Has anyone tried to build a translational bridge using a 2612 before? Is is preferable to use a 3600 or more heavy router (7200?) I have a 7200 but then I cannot turn of IP routing.... The 7200 is the corerouter at this moment.
config:
(old)5500 (bridge 0x1) with Tokenring (ring 15, subnet 10.128.112.0 mask 255.255.240.0) and ethernet (other subnet)
7200 Core (tokenring, ethernet, lots of serials)
(new)6509 MSFC With Ethernet modules (connected on vlan with subnet 10.128.96.0, subnet 10.128.112.0 is routed through the MSFC)
Cisco 2612:
no ip routing
source-bridge ring-group 10
source-bridge transparent 10 11 3 15
int e0/0
ip address x.x.x.x
source-bridge 3
int t0/0
ip addres x.x.x.x
source-bridge 15 3 10
source-bridge spanning
bridge 3 protocol ieee
I have build lots of enterprisenetworks using CATS6500, 7200 routers, VPN's etc and I can't build a simple bridge.... please help before I start a carpenter company.. :-)
