This GSR and couple of other routers do internet transit and peering, and
are dual connected to the 2 x 7600 at the core.  a bunch of access/customer
routers at the other end are also dual-connected to the the 7600s.  thats
the reason for keeping a separate router to terminate the 2Gbps link in
question.   ie:

3 x TRANSIT/PEERING ROUTERS-----2 x 7606-----n x
ACCESS_ROUTERS-----CUSTOMERS



However while looking at pricing options, the 'POS OC48 Engine 3 card' for
the GSR, specifically  'OC48X/POS-LR-SC'  comes at a list price of USD
99,000

Interestingly thats more $$$ than a 7606 chassis with SUP720-3BXL, dual PSU,
6704-10GE linecard and optics.


Now I understand that Engine 3 on GSR has some more features than 'plain'
ports on the 7600, but such a high price for the GSR card is beyond my
understanding.

It almost makes more sense purchasing an entire 7600 system and get 10GB
ethernet, rather than one card for the GSR for the same money!!

Anyone care to point out what I'm missing here ?



Thanks
