Subject: DLSW Cost
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"
decrease 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 learned from another devices dlsw local peer
command.
The following is "show" :
R1:
R1#sh dlsw cap
