Problem adding interfaces in Multilink-Cisco 7609

Hi All,

I have a problem bundling interface in a multilink on cisco 7609. When the interface in the same module are bundled in a multilink it works well but the problem is when i bundle interfaces on different modules the serial interfaces shows line protocol down.

interface se1/1/1:0 + se1/1/2:0 : multilink works well

interface se1/1/1:0 + se2/1/1:0 : multilink misbehaviour

IOS version adventerprisek9-mz.152-4.S1.

interface Serial1/1/1:0

bandwidth 2048

no ip address

encapsulation ppp

ppp multilink

ppp multilink group 10

ppp multilink endpoint string 10

interface Multilink10

dampening 30 500 1000 120 restart 500

ip address x.x.x.x

no ip redirects

no ip unreachables

no ip proxy-arp

ip pim sparse-mode

ppp multilink

ppp multilink group 10

no cdp enable

 

Regards,

Sathvik

May not be a problem per se, but rather how Cisco Implemented MLPPP (wan protocol) on what is essentially a LAN swtich.

Hi Vmiller,

Sorry for the delayed response.

Could you some  documents  which would help me understand MLPP better.

Hi,

Are the serial endpoint strings on each serial interface unique?

example

interface Serial1/1/1:0

ppp multilink endpoint string ser-1110

interface Serial1/2/0:0

ppp multilink endpoint string ser-1200

interface Serial2/1/1:0

ppp multilink endpoint string ser-2110

Cheers,

Brian
