Hi, I can't seem to find any documentation about setting up squid with WCCPv2 and multiple cisco routers. So this might be good for the archives if someone helps me out here.
I've got WCCP running between 1 router and a Cisco router. Now I want to add routers. I've tried the following Add another router entry in squid.conf wccp2_router 192.168.0.6 wccp2_router 192.168.48.48 Create another GRE tunnel ip tunnel add wccp0 mode gre remote 172.31.255.48 local 10.1.250.10 dev eth0 ip addr add 10.1.250.10/32 dev wccp0 ip tunnel add wccp1 mode gre remote 172.31.255.6 local 10.1.250.10 dev eth0 ip addr add 10.1.250.10/32 dev wccp1 ip link set wccp0 up ip link set wccp1 up I've configure the two routers similar global config: ip wccp web-cache and one inside interface: ip wccp web-cache redirect in This is not doing what I needed The cisco is seeing WCCP packets but they are not correct: Jul 24 14:53:32.388: WCCP-PKT:S00: Sending I_See_You packet to 10.1.250.10 w/ rcv_id 00000003 Jul 24 14:53:42.393: WCCP-PKT:S00: Ignored duplicate Here_I_Am packet received from 10.1.250.10 Jul 24 14:53:52.393: WCCP-PKT:S00: Ignored duplicate Here_I_Am packet received from 10.1.250.10 Jul 24 14:53:57.389: WCCP-PKT:S00: Sending Removal_Query packet to 10.1.250.10w/ rcv_id 00000004 Jul 24 14:54:02.389: %WCCP-1-SERVICELOST: Service web-cache lost on WCCP client 10.1.250.10 Jul 24 14:54:02.393: WCCP-PKT:S00: Sending I_See_You packet to 10.1.250.10 w/ rcv_id 00000005 Jul 24 14:54:12.393: WCCP-PKT:S00: Ignored duplicate Here_I_Am packet received from 10.1.250.10 Jul 24 14:54:22.394: WCCP-PKT:S00: Ignored duplicate Here_I_Am packet received from 10.1.250.10 Jul 24 14:54:27.394: WCCP-PKT:S00: Sending Removal_Query packet to 10.1.250.10w/ rcv_id 00000006 Jul 24 14:54:32.394: %WCCP-1-SERVICELOST: Service web-cache lost on WCCP client 10.1.250.10 Jul 24 14:54:32.398: WCCP-PKT:S00: Sending I_See_You packet to 10.1.250.10 w/ rcv_id 00000007 Jul 24 14:54:42.398: WCCP-PKT:S00: Ignored duplicate Here_I_Am packet received from 10.1.250.10 sh ip wccp web-cache detail: WCCP Client information: WCCP Client ID: 10.1.250.10 Protocol Version: 2.0 State: NOT Usable Initial Hash Info: 00000000000000000000000000000000 00000000000000000000000000000000 Assigned Hash Info: 00000000000000000000000000000000 00000000000000000000000000000000 Hash Allotment: 0 (0.00%) Packets s/w Redirected: 0 Connect Time: 00:00:29 Bypassed Packets Process: 0 Fast: 0 CEF: 0 A tcpdump reveals the squid proxy is sending out UDP:2048 packets to both routers which seems right? 14:53:02.414230 IP 10.1.250.10.2048 > 192.168.0.6.2048: UDP, length 152 14:53:02.414281 IP 10.1.250.10.2048 > 192.168.48.48.2048: UDP, length 152 14:53:02.415322 IP 192.168.0.6.2048 > 10.1.250.10.2048: UDP, length 92 14:53:07.406771 IP 192.168.48.48.2048 > 10.1.250.10.2048: UDP, length 64 14:53:12.414837 IP 10.1.250.10.2048 > 192.168.0.6.2048: UDP, length 152 14:53:12.414866 IP 10.1.250.10.2048 > 192.168.48.48.2048: UDP, length 152 14:53:12.415705 IP 192.168.48.48.2048 > 10.1.250.10.2048: UDP, length 92 14:53:17.415196 IP 10.1.250.10.2048 > 192.168.0.6.2048: UDP, length 348 14:53:17.415248 IP 10.1.250.10.2048 > 192.168.48.48.2048: UDP, length 348 14:53:22.415505 IP 10.1.250.10.2048 > 192.168.0.6.2048: UDP, length 152 14:53:22.415536 IP 10.1.250.10.2048 > 192.168.48.48.2048: UDP, length 152 14:53:27.413021 IP 192.168.0.6.2048 > 10.1.250.10.2048: UDP, length 64 14:53:32.416171 IP 10.1.250.10.2048 > 192.168.0.6.2048: UDP, length 152 14:53:32.416209 IP 10.1.250.10.2048 > 192.168.48.48.2048: UDP, length 152 14:53:32.417105 IP 192.168.0.6.2048 > 10.1.250.10.2048: UDP, length 92 14:53:37.415066 IP 192.168.48.48.2048 > 10.1.250.10.2048: UDP, length 64 14:53:42.416840 IP 10.1.250.10.2048 > 192.168.0.6.2048: UDP, length 152 14:53:42.416870 IP 10.1.250.10.2048 > 192.168.48.48.2048: UDP, length 152 14:53:42.417544 IP 192.168.48.48.2048 > 10.1.250.10.2048: UDP, length 92 14:53:52.417504 IP 10.1.250.10.2048 > 192.168.0.6.2048: UDP, length 152 14:53:52.417540 IP 10.1.250.10.2048 > 192.168.48.48.2048: UDP, length 152 14:53:57.413797 IP 192.168.0.6.2048 > 10.1.250.10.2048: UDP, length 64 Any suggestions on how the configuration should be done?
