Hi, ccielab#!
I am setting dlsw on my lab. The following is my config:
R1:
dlsw local-peer peer-id 1.1.1.1
dlsw remote-peer 0 tcp 2.2.2.2 cost 1
dlsw remote-peer 0 tcp 3.3.3.3 backup-peer 2.2.2.2
dlsw bridge-group 1
R2:
dlsw local-peer peer-id 2.2.2.2
dlsw remote-peer 0 tcp 1.1.1.1
dlsw bridge-group 1
R3:
dlsw local-peer peer-id 3.3.3.3
dlsw remote-peer 0 tcp 1.1.1.1
dlsw bridge-group 1
I think you can understand my config. I want to let "remote-peer 2.2.2.2" decre
ase its cost. But when I show the "dlsw cap" on r1 & r2, I see the cost is not
change. When I decrease the cost on "local-peer", I can see the change.
I find the following words on cisco site:
Although configuring cost on a peer is not required, it can be used to control
which path the sessions use. Cost can be specified on either a dlsw local-peer
or a dlsw remote-peer command. When specified on a dlsw local-peer command, it
is exchanged with remote DLSw+ peers as part of the capabilities exchange. The
cost configured on the dlsw remote peer command overrides any cost value learne
d from another devices dlsw local peer command.
The following is "show" :
