Hello All,
can anyone please tell me how to create a layer 3 ether channel ?
i have made layer 2 etherchannels, but i am unable to create a layer 3 etherchanel.
i am trying to create a layer 3 etherchannel b/w a multi-layer switch and 2811 router on packet tracer.
Multi-layer-switch
================
ms(config)#interface range fa 0/1 - 2
ms(config-range-if)#channel-group 1 mode on
ms(config)#interface port-channel 1
ms(config-if)#no switchport
ms(config-if)#ip address 192.168.1.1 255.255.255.0
Router
=======
R(config)#interface range fa 0/1 - 2
R(config-range-if)#channel-group 1 mode on
R(config)#interface port-channel 1
R(config-if)#no switchport
R(config-if)#ip address 192.168.1.2 255.255.255.0
one more thing , can we use lacp or pagp for layer 3 etherchannel or are they only for layer 2 etherchannels ?

The config looks ok. Is it not coming up? You may need to enable ip routing on the switch. Also etherchannel can be fussy, and you may need to "bounce" it a couple of times on either side to get it to come up clean. Also verify the port channel config (like no switchport) gets copied down to the interfaces.
And don't forget your no shuts! :P -

What does show etherchannel summary show? show int fa0/1 and show int port? Do you have anything else configured on one of the interfaces?CCNP :study:
