How to create a Point to Point VLAN-VLAN connection with two IRS 4451-X

[Julio E. Moisa]

Hi

A point to point represents the connection between 2 interfaces from different routers, have you using any Switch ethernet module. 

Ethernet Switch
NIM-ES2-4	Yes	Yes	Yes	Yes	Yes	16.4.1	3.15	Cisco 4-Port Gigabit Ethernet Switch NIM
NIM-ES2-8	Yes	Yes	Yes	Yes	Yes	16.4.1	3.15	Cisco 8-Port Gigabit Ethernet Switch NIM
NIM-ES2-8-P	Yes	Yes	Yes	Yes	Yes		3.15	Cisco 8-Port Gigabit Ethernet Switch NIM with PoE Support
SM-X-ES3-16-P	Yes		Yes	Yes			3.10	16-port POE layer 2/3 EtherSwitch Service Module Data Sheet    Q&A
SM-X-ES3-24-P	Yes		Yes	Yes			3.10	24-port POE layer 2/3 EtherSwitch Service Module Data Sheet    Q&A
SM-X-ES3D-48-P	Yes		Yes				3.11	48-port POE layer 2/3 EtherSwitch Service Module Data Sheet    Q&A

Router1 fa0/0 --------- fa0/0 Router2

The config could be, for example:

ROUTER 1

vlan 100

interface vlan 100
ip address 10.0.100.1 255.255.255.252
no shut

interface f3/1
description TO-ROUTER2
switchport
switchport access vlan 100
switchport mode access
no shut

ROUTER 2

vlan 100

interface vlan 100
ip address 10.0.100.2 255.255.255.252
no shut

interface f3/1
description TO-ROUTER1
switchport
switchport access vlan 100
switchport mode access
no shut
