Re: Enable CEF on ISDN 802 Router

hi,

Unfortunately, it seems that the 802 doesn't support CEF.

Always use "Cisco Feature Navigator":

Hi,

use "ip cef" in the global configuration.

What is your IOS, please do "show ver" ?

Re: Enable CEF on ISDN 802 Router

ip cef does not work

I'm running 12.1(3)XG5 and 12.2(37) on the routers.

I'm trying to add the command, "ip verify unicast reverse-path" and it tells me to enable CEF first, so it this IOS must support it

router(config-if)#ip veri u r

% CEF not enabled. Enable first

router(config)#ip cef

^

% Invalid input detected at '^' marker.
