SMLT - Config VSP 4450 + ERS4926

[Julio_Oliveira]

Hi All,

I have 2 VSPs 4450 connected via V-IST working good.

I am trying to connect a ERS in both VSPs with MLT.

ERS = Standard MLT (Ports 1 and 2)

VSPs = SMLT (Port 12 each switch)

When I leave MLT connection on the VSP as standard it works good but when I enable the SMLT I lost connection.

Any suggestions?

MLT 1 looks fine (it's configured as SMLT). Although you mentioned ports 1/12 should be the members of the MLT and there are four members 1/11, 1/12 on both VSPs.

Please show us also output of "show isis spbm" from both VSPs.

Post an output of "show mlt" command from all three switches.
