ip tcp adjust-mss on LAN and BVI

[johnlloyd_13]

hi all,

just a quick question, we got routers configured with LAN interface and bridged to a BVI interface.

i want to set the ip tcp adjust-mss 1420 but which port will take precedence?

my question, which port do i configure this command?

interface FastEthernet0/0.2 
 description ### Corp LAN ###
 encapsulation dot1Q 2
 no ip redirects
 ip accounting output-packets
 ip nbar protocol-discovery
 ip tcp adjust-mss 1420   <<<

interface BVI2
 description ### Corp VLAN ###
 ip address 192.168.231.1 255.255.255.0 
 ip flow ingress

Since this command works at the IP layer, you will need to apply it to the routed interface. That will be BVI2 in this case. Regards, Mike
