Hi,
Question on configuring "carrier-delay" on LAN interface
I have two router A & B on the same LAN forming ISIS neighbor.
The question is to ensure convergence time is as fast as possible while link
down detection is also as fast a possible.
One way to improve the convergence is to set the hello timer to minimal "isis
hello-interval minimal "
To make the link down detection as fast as possible, can I configure the
"carrier-delay msec 0" on the LAN interface? Will it work?
Reading the Cisco documentation, it says this command applicable only to
serial interface.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cr/hif_r/int_a1h.htm#wp1199046
But IOS still allow me to configure it on LAN interface
Rack1R2#sh run int fas 0/0
Building configuration...
Current configuration : 104 bytes
!
interface FastEthernet0/0
no ip address
*carrier-delay msec 0*
duplex half
no clns route-cache
end
Rack1R2#
Please advice
Regards
Pandi
