Good afternoon. After lots of searching, I found that bridging over GRE tunnels is configurable, but unsupported. (yes, really: +++++++++ cr1-5509-rsfc-1(config)#bridge 1 protocol ieee cr1-5509-rsfc-1(config)#int tu0 cr1-5509-rsfc-1(config-if)#bridge-group 1 1d04h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to down % This command is an unreleased and unsupported feature cr1-5509-rsfc-1(config-if)# 1d04h: Note: A random Spanning Tree Bridge Identifier address of 0000.0c92.7210 has been chosen for Bridge Group 1 since there is no mac address associated with the selected interface. 1d04h: Ensure that this address is unique.
cr1-5509-rsfc-1(config-if)# +++++++++ Anyone here have experience with this? RSFC in a Catalyst 5509, IOS 12.1 (that's the only IOS on RSFC's). Anyone have comments on stability found or not found? If this works, it means the RSFC's in my 5500's have just gained a new lease on life. -- Lamar Owen Chief Information Officer Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 http://www.pari.edu _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
