HI
Dear all
I have a problem of understanting the concept of LINE CARD on a router. On our network we are running C7203 and C7209 routers. The maximum sessions are :
• Maximum number of IP and PPPoE subscriber sessions supported per line card is 16000.
I want to know if we buy additionnal card the number of PPPoE subscriber sessions supported will be multiplied by 2.
Here is my problem. We have have connected a DSLAM of 862 subscribers behind a C7203 router. We translate private ip addresses with a pool of 30 public ip addresses and we have a CPU usage of 72%.
We have 5 others DSLAMs connected to a switch . These 5 DSLAMs support 4500 subscribers. Is it possible by buying 3 additionnal line cards on my C7609 to have 64 000 sessions.
Also when CISCO says
• Maximum number of IP and PPPoE subscriber sessions supported per line card is 16000
does it means that in my case i have to connect each DSLAM on one particular line card?
Is it possible to connect the cable from my switch on a C7609 router (with 3 additionnal line cards ) and have a maximums PPPoE subscribers sessions of 64000
Thx
