CSCud38433
Symptom:
The router is unable to establish MPLS neighborship or ping the destination loopback
interface.
Conditions:
Occurs when you configure two Equal Cost Multipath (ECMP) paths on a bridge
domain interface (BDI) using static routes.
Workaround:
The following workarounds exist:
–
Use Interior Gateway Protocol (IGP) instead of static IP routes.
–
Shut down one of the ECMP paths.
•

Conditions:
Occurs when the bridge-domain contains EFP interfaces, some of which are on a
port-channel. The issue can also occur after a router reload.
Workaround:
Issue a
shutdown
/
no shutdown
on the BDI interface.
•

One link from a copper Ethernet interface to an SFP Ethernet interface
Workaround:
Issue a
shutdown
/
no shutdown
on copper-to-copper connection interfaces.
