Hi Diva,
I feel I need some more information on this..
1. Are all 4 nodes part of the same network, i.e., are the India and UK end
nodes back connected?
ALL NODES ARE PART OF THE SAME NETWORK BUT ARE NOT BACK CONNECTED.
2. Are they having just 1 IPLC each?
YES ONE EACH OF THE IPLCS ARE CONNECTED TO EACH OF THE MGX8850
3. If they are having more than 1 IPLC, are you running PNNI or some other
routing protocol on them, or have you done some static mapping?
THEY HAVE ONLY ONE IPLC EACH, BUT THEY HAVE BEEN CONFIGURED WITH PNNI
4. Do you mean to say that you have 2 routers running HSRP and they are
attached to different FRSMs on FR? And then on in case of one IPLC going
down you want the traffic to route through the other IPLC?
YES WE HAVE TWO ROUTERS RUNNING HSRP , AND THEY ARE ATTACHED TO TWO
DIFFERENT FRSM ON TWO DIFFERENT MGX8850.
AND INCASE OF IPLC FAILURE ON ONE MGX , THE ROUTER CONNECTED TO THE FRSM ON
THAT MGX 8850 SHOULD DETECT THAT AND THEN THE HSRP SHOULD REDUCE THE
PRIORITY.
On the last point, as per me it would be better to connect your MGX nodes
to
each other locally at both the locations and then by running PNNI
end-to-end
you can route your traffic in case of IPLC failures, and more so if both
the
nodes are sitting close by. For your traffic routing you can rely upon on
some IP routing features.
IT IS NOT POSSIBLE TO BACK CONNECT THE MGXs BECAUSE THEY ARE NOT IN ONE
SINGLE LOCATION.
AND THE CUSTOMER WANTS TO USE ONLY STATIC ROUTES AND NO DYANAMIC PROTOCOL.

Hi,
Let me expalain my network now.
I have two MGX8850s in India on to which one IPLC each are getting
connected to the PXm1-e1 card.The other end of the IPLC s are connected
similarly to two MGX8850s in UK.
We have a FRSM card on each of the MGXs .We have 4 cisco 3745 routers
connected using a pair of DTE and DCE cables.
The serial interface is configured for framerelay.I have not created any
subinterfaces on the serial interface for framelrelay. The routers are
configured with HSRP. I would like the HSRP to track the changes in the
status of the IPLC and switch over the HSRP active router. Right now, when
the IPLc goes down, the FRSM card still shows up and the router serial
interfaces shows line protocol up.Thus HSRP , which is tracking the serial
interface still assumes that the link is up and hence will not change the
state.
My objective is :---
The serial interface connected to the FRSM on the MGX should be able to
know when the IPLC connected to PXM1-e1 goes down.And the HSRp which is
tracking the serial interface should change the state .
Thanks and Regards

HI Diva,
I think your query is more towards the FR interfaces than the MGX nodes. As
per me, as soon the IPLC or the trunk link on the MGX goes down, it will
also make the FR connection down, and same will be reflected on the PVC
status in router also. So that should serve your purpose, but then what is
your interface configuration, are you using sub-interface or the PVC is
configured on to the main interface itself. Let us know about your core
objective and some more information, and then may be things take some new
turn.

Hi,
We have two MGX 8850s to which one IPLC each are connected. The MGX8850
also has a FRSM-HS2 card using which a router is connected to each of the
MGX8850s.
How do we let the router's serial interface know that the IPLC is down? As
of now , even if the IPLC is down, the serial interface show line protocol
up.
IS there any way by which we can let the Router's serial interface know
that the IPLC connected to the MGX8850 is down?
Thanks and Regards
