Hi guys,
Hope you could help me on this. Some days ago found that a vrf label of a VPLS was mapped to 2 different LSI interfaces each corresponding to a different VRF and actually a different logical system:
1 label mapped to 2 different LSIs:
> show route forwarding-table label 262147
Routing table: default.mpls
MPLS:
Destination Type RtRef Next hop Type Index NhRef Netif
262147 user 0 Pop 2195 2 lsi.1049345
Logical system: MIAV
Routing table: default.mpls
MPLS:
Destination Type RtRef Next hop Type Index NhRef Netif
262147 user 0 Pop 2759 2 lsi.17826311
VPLS 1:
> show vpls connections instance vpls-CUSTOMER-A
Instance: vpls-CUSTOMER-A
Edge protection: Not-Primary
Local site: MIA
connection-site Type St Time last up # Up trans
3 rmt Up Jun 1 18:27:05 2016 1
Remote PE: 10.10.10.31, Negotiated control-word: No
Incoming label: 262147, Outgoing label: 262210
Local interface: lsi.1049345, Status: Up, Encapsulation: VPLS
Description: Intf - vpls vpls-CUSTOMER-A local site 2 remote site 3
VPLS 2 (in logical system):
> show vpls connections instance vpls-CUSTOMER-B logical-system MIAV
Instance: vpls-CUSTOMER-B
VPLS-id: 3793
Neighbor Type St Time last up # Up trans
10.0.120.204(vpls-id 3793) rmt Up Jun 1 18:27:13 2016 1
Remote PE: 10.0.120.204, Negotiated control-word: No
Incoming label: 262147, Outgoing label: 262194
Negotiated PW status TLV: No
Local interface: lsi.17826311, Status: Up, Encapsulation: VLAN
Description: Intf - vpls vpls-CUSTOMER-B neighbor 10.0.120.204 vpls-id 3793
Flow Label Transmit: No, Flow Label Receive: No
I have 2 particular questions here...
1) How is equipment determining to which LSI will traffic be mapped to?
2) Is this normal behavior? Shouldn't be a unique label allocated to a VRF despite it being on default or user logical system? Don't they all share a common forwarding plane?
Thanks in advance.
