I have four T1 configured as MFR via MPLS. See below the config given by
Telco. One Point-to-Point sub-interface is used for Internet traffic,
while the
otherone is used for private branch locations.
Technically, if one T1 goes down in a bundle, the traffic shouldn't be
interrupted, and should flow via other 3 T1s in the bundle. But it is
weird that whenever one T1
goes down the whole network goes down. Telco is blaming on Cisco
Router, and to date no one has
clue.
I have tested couple of times such as reloading the router, and noticed that
all the serial interfaces came up automatically except the , 3rd
s0/1/0:0status up/down. Eventhough the
other three interfaces came up, but still nobody couldn't get out to the
Internet, and branch offices. I had to
manually shut down the interface, and brought it up back twice in order
to bring the interface, and restored the flow of
traffic.
Any urgent help will be appreciated.
