if there are two equal cost ISIS routes, then there will be two LSP's for a FEC. but in MPLS only one FEC should be used. on what basis will this selection be made? can we balance load across links in a port channel in MPLS, how? also in VPLS scenario will these load balancing result in disordering of packets on Pseudo wire?

hi Anand, it would be really helpful if you tell me the tables and ID's to look into when tracing the end to end traffic by capturing packets. thank you.

hi in my network, I have a switch (D) connected to multiple switches(A1,A2,...) and the VLAN's repeat in each of these switches (A1,A2,..). I want to use MPLS layer2 VPN concept here. please tell me should I go with VLL or VPLS and why? also if possible please suggest any document wherein I can get detailed info on VLL and VPLS. thank you.

ok. I have configured service instances on EtherChannel group. So you mean to say that after creating a service instance on a EtherChannel, the switchport mode trunk command is not allowed on the interface.

hi, so in that case the following configuration is incorrect: interface GigabitEthernet0/1 switchport trunk allowed vlan none switchport mode trunk channel-group 1 mode on the customer facing interfaces should not be in trunk mode, right??

hi, but the document says that a trunk port always on ingress removes the outer tag, it then adds the VLAN tag of the broadcast domain, and then it does match a service instance.

Hi Vasilii, say If traffic at the int 1 and 2 has a tag, what will be the sequence of operations and what role the service instance and bridge domain has to play there? I also referred this document http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/12-2_52_ey/configuration/guide/3800x3600xscg/swevc.html#wp1035924 now I am confused. please suggest what should I configure under my scenario?
