Multilink frame relay + E1 link

[Luis Nunez Mejias]

Hi fellas, I need some help in configuring multilink with a 512 kbps frame relay link and a E1 leased line. It turns out that a new service provider it's offering E1 leased lines with no encapsulation and I already have a 512 kbps frame relay link. Below I'll show the config of both links on both sides and plz I need your cooperation to create a multilink.

I really appreciate your help.

HI Luis

If i understand you correctly, are you asking to bundle a E1 link and a 512 frame-relay link together in multilink? IF so you cannot do that.

IF the new provider does not support frame-relay then you can take that config out and configure it for e1 link just like you have for 0/0/1.

You can bundle two e1 links using mutilink but you cannot bundle a frame-relay link and e1 link together.

Hope i understood you correctly.

Thax a lot for your answer Ray. So what can I do for load balance those two links (E1 and FR). Right now one of them (FR link) it's in fail over because of EIGRP metrics choice. There's no way I can use both of 'em?

Lan,

You cannot bundle a frame-relay and a E1 using multilink.

IF you want to load balance the traffic between the two links you can use protocol base load balancing or policy base routing.

I would suggest that you open a case with Cisco TAC and they will help you configure it and set it up.

Thank you

Ray
