7750 SR-1 as a BNG question

Post by jeansalim »


I am planning to make a 7750 SR-1 as a BNG. Can anyone help with the hardware requirements? especially regarding the multiservice ISA card.

You don't need necessarily an ISA for BNG. Unless as part of the service you need to do NAT/IPSec tunnel termination/LNS etc. For things like regular termination of PPPoE subscribers it's not needed. I don't believe there is an ISA card for the MDA-e-XP slots of an SR-1.

It's then a matter of you undertstanding your scaling requirements (such as bandwidth, number of subscribers, number of queues per subscriber etc) and whether the hardware limits of the single IOM-5e embedded in an SR-1 are enough for you.
