Basic point of the question is to make us aware of the fact that we can create a sub-interfaces on a FastEthernet with Dot1q encapsulation of the Vlans created and passed between the switches. Keeping that in mind we can proceed to troubleshoot in the following manner:
1] Check the Router Sub-interface's config for dot1q encap [native & non-native] and IP addressing & then Router Eigrp config. 2] Check the Switch config for the interface connecting the router and as well as the Vlan passing between the switches [Since this Lab starts with MST config passing of vlans over trunks properly needs to be checked properly]. You could create a temporary Vlan SVI's of the troubling Vlans on the switch [Sw3 in this case] and then try pinging the addresses [since all devices are running Eigrp and therefore should be reachable]. You could try various debug like "debug ip packet", "debug ip icmp" [when trying to ping]. ----- Original Message ----- From: "K Ploited" To: [email protected] Subject: [OSL | CCIE_RS] Vol 1 Lab 3 task 3.15 Date: Sun, 16 Aug 2009 19:46:09 +1000 Hi, I have a trouble with this task where my R9 - when created sub-interfaces with dot1q (vlan 12,40,567,2200,2300) - can only communicate with R8 (Vlan 2200). So, the eigrp can only get 200.0.0.8 not the rest. Could you please advise how I can troubleshoot this ? Thanks.
