Problem:
So I was working on implementing WCCP redirection for networks to get TCP accelerated between two data centers and I ran into a problem. The problem was that subnets behind the core switches were not getting WCCP redirected into the WAAS units. So I wonder why? It’s matching the redirect-list ACL and shows up in [...]
WCCPv1:
————————
1. Only single router can participate in a cluster of WCCP-capable devices
2. Intercepts and redirects HTTP and HTTPS
3. Does not allow load balancing
WCCPv2:
————————
1. Supports multiple routers can redirect to clusters and devices, allows for load balancing.
2. Support for non HTTP and HTTPS protocols such as other TCP or UDP packets.
3. Capable of MD5 authentication.
4. Notification [...]
This option allows 6500/7600 to use hardware acceleration for WCCP packets in Layer 2. This method in theory allows you to utilize up to 3Gbps of traffic on a PFC2 card, perhaps even more with a PFC3B.
The device (eg: WAE or ACNS) needs to have layer 2 adjacency with the 6500 switch in order to [...]
