MLP LFI virtual template

PAUL CHEN · ‎10-27-2009

Hi,

I configured LFI and I am not sure what the interface virtual-template 101 ip address should be ?

CCO documents usually use a ip unnumbered ethernet for the virtual-template.

In this scenario, a LAN interface is not available.

The config below works though:

interface Serial0/0/1.1 point-to-point

bandwidth 384

ip address 10.10.111.1 255.255.255.0

ip ospf mtu-ignore

snmp trap link-status

frame-relay interface-dlci 201 ppp Virtual-Template101

class frts-384

interface Virtual-Template101

bandwidth 384

ip address 10.10.111.1 255.255.255.0 <-------------- what ip address should be configured here ?

ppp multilink

ppp multilink interleave

ppp multilink fragment delay 10

service-policy output hq

!

Any help appreciated.

Thank you.

Paul

Hi Paul,

You can use any IP address because it's a PPP link. The idea is just to activate the IP stack. We recommend to use the addresss of another interface so you don't have to use a new one. Usually a loopback works perfectly as this interface never get down.
