Router Installation and Configuration Manual/Configuring Bridging
From ImageStream Router Documentation
bridge-group (bridge group) - Adds the interface to the bridge group
New bridge-group commands include: ex: bridge-group 16 spanning-disabled
spanning-disabled - Disables the spanning tree algorithm for the bridge group
priority (prio) - Sets the bridge port priority for this interface
path-cost (cost) - Set the port's path cost (values 1-65535)
New bridge commands (global bridge configuration)
ex: bridge 16 aging-time 300
spanning-disabled - Disables the spanning tree algorithm for the bridge
priority (prio) - Sets the bridge priority
path-cost (cost) - Set the bridge's path cost (values 1-65535)
aging-time (seconds) - Sets the bridge's aging time (values 1-1000000)
forward-time (seconds) - Sets the bridge's forwarding time (values 1-200)
hello-time (seconds) - Sets the bridge's hello time (values 1-10)
max-age (seconds) - Sets the bridge's maximum aging time (values 10-200)
Each bridge group automatically provides an interface to allow configuring IPs
and routing for the bridge. The interface will be named bvi(bridge group). So
if you have a bridge-group 16 you'll be able to configure interface bvi16.
Here's a quick example:
interface Serial0 description SuperLine Shelf encapsulation frame-relay ietf frame-relay mode dce ! interface Serial0.16 description DLCI 16 (10.10.16.0) frame-relay interface-dlci 16 bridge-group 16 ! interface Serial0.17 description DLCI 17 (10.10.17.0) frame-relay interface-dlci 17 bridge-group 17 ! interface Serial0.18 description DLCI 18 (10.10.18.0) frame-relay interface-dlci 18 bridge-group 18 spanning-disabled ! interface bvi16 ip address 10.10.16.1 255.255.255.0 ! interface bvi17 ip address 10.10.17.1 255.255.255.0 ! interface bvi18 ip address 10.10.18.1 255.255.255.0 ! # Change the forwarding delay to 3 seconds bridge 16 forward-time 3 # Change the hello interval to 10 seconds bridge 16 hello-time 10
