Metro Ethernet links supports layer 3 etherchannel ??

[timothyquito]

We got two sites, they're connected using two Metro Ethernet links (from different ISP) - for primary and back up connection.

Links are currently configured as L3 (point-to-point). With our existing setup, is it possible to aggregate those links? 

See attachment for reference (red line - ISP 1 , blue line - ISP 2)

Any information would be greatly appreciated. Thanks!

Hi,

What platform is Corsw1?. if both the platforms support channel-group, you can make those physical ports as member link to a port-channel and configure an IP address on the port-channel.

With this, you wont need 2 different IP addresses. But it will be difficult to control the traffic flow over a specific member link (which may be a bit easy to do with L3 interface).

Hello Nagendra, 

Thanks for the response. Both switches are WS-C6509-E and running IOS Version 12.2.

BTW I'm more concern with ISP's devices located in between of core switches. Also if we need to request any setup change from our service providers.

Thanks,

Tim
