I have a 7507 with RSP4 and IOS 12.2(26) Service Provider. This router are terminate 1600 ATM VCs with RBE.
On my standard configuration the sub-interface has the following configuration:
interface ATM1/0.32 point-to-point
ip unnumbered Loopback0
ip helper-address XXX.XXX.XXX.XXX
atm route-bridged ip
pvc 10/32
encapsulation aal5snap
All works fine until I configure some (300) point to point interfaces for users with range of fixed IP address. This subscribers hava the following configuration template:
interface ATM1/0.1572 point-to-point
ip address XXX.XXX.XXX.XXX 255.255.255.248
atm route-bridged ip
pvc 6/823
encapsulation aal5snap
This router have only one static default route to border router to Internet.
My problem is the performance. The customer are experience slow access to Internet, and the ping to the customer PC show slow response time (600ms).
After reload, the router return to the normal performance, but after 6 hours the customers experience slow performance again. I allways disable CEF but without results. The router show CPU utilizatin under 30%.
Anyone can help me ?
Thank's in advance
