Branch router is connected to Central Office via IPsec tunnel, on LAN interface there is ip wccp 61 redirect in configured. Where should the ip wccp 62 redirect in be configured - on the physical WAN interface or on the tunnel interface or should I configure ip wccp 61 redirect in and ip wccp 62 redirect out on the router's LAN interface? Can there be some negative impact if redirection is configured on virtual tunnel interface or physical interface with crypto map applied?
Hi regarding this question, you may configure the service 61 out and 62 in on the WAN interface, but need to remember to configure the ip wccp redirect exclude in on the interface where the WAAS appliance is connected to in order to avoid a possible loop. As well remember that the egress ( redirect out) may lead to high CPU utilization on the router since it will get the traffic leaving the router and switch it back in order to perform the inspection for WCCP and to realize if the packet needs to be redirected to WAAS.
This works well, even though Cisco recommends to use redirect 61 in on the LAN interface and 62 in on the WAN interface for a better performance on the router.
常见的数据中心之间通信均会采用运营商MSTP/OTN专线进行互联实现通信，由于长途线路价格昂贵通常我们需要最大化使用线路带宽，传统的网络传输中通常是尽力而为传输一旦突发流量较大就会发生线路拥塞的情况，从而影响业务正常通信传输。这时候我们可以采用Qos技术来实现数据中心思科设备之间关键网络流量保障，从而实现链路最大化利用。拓扑图场景如下：如上图，SW01是位于数据中心A的广域网接入Cisco Nexus 3048交换机，SW02是位于数据中心B的广域网接...
