There are two 7206 in two cities. Each has PA-STM1.
Connecting two 7206 to each other is done via SDH, then PPP Multilink bundle with 8xE1 in it was set up. It is maximum quantity of E1 for multilink interface. So, I have 16mbit/s link.
I want to expand my link. It's impossible to set up the second Multilink because Cisco says:
029778: May 23 19:25:30.714 ALM: Se2/0.1/1/4/2:0 MLP: Request add link to bundle
029779: May 23 19:25:30.714 ALM: Se2/0.1/1/4/2:0 MLP: Adding link to bundle
029780: May 23 19:25:30.714 ALM: Serial2/0.1/1/4/2:0 MLP: Local MRRU or peer MRRU does not match that of bundle akt-oup0-bb1
Is the solution to unset the Multilink to separate 8 interfaces, to add, for example, 8 E1 more, to assign p2p addresses to each pair and to do load balancing between 16 parallel p2p's??
Or are there any other ways?
OK. It seems the documentation applies to older IOS but there are now in 12.4 novel waysto discriminate among bundles.
interface multink 1
ppp multilink endpoint string
Also, seems you can set a larger number of links now:
ppp multilink links maximum 16
and in global config:
multilink bundle-name rfc
I understand that all this is quite confusing, unfortunately I don't have an adequate platform to test that now.
