I had this problem a few weeks ago and can't explain what I saw/experienced. We had a device which was connected via Fiber , but it was not pingable, even thou the interface status was up up.

Primary VLAN 100. VLAN 101 and 102 are community VLAN that belong to VLAN 100. VLAN 200 is not associated with any other vlan. Can VLAN 200 access to VLAN 101 as long as there is inter vlan routing and no ACL that is blocking?
I set up MPLS on GNS3, however, when I go to create a virtual circuit via the 'xconnect' command, the encapsulation type of 'mpls' is not available. The only type available is 'l2tpv3'. Is this a limitation of the c3745 or?
I'm wondering what functionality this command gives? tunnel mpls traffic-eng fast-reroute "node-protect" FRR local protection can be either link or node, node is preferred by default.

Hi, Just looking for some advice with regards to hardware for passing SWITCH. I passed it a few years ago and just want to renew it to keep the CCNA status ticking over. From my old lab i still have 2x3550 + 2x2950 with a couple of routers too. I'm looking at replacing these with 3750's but wanted to know if these will be…
I have a question on how VPN can be configured on OSPF vs BGP. Are VPN interchangable with routing protocols? I am confused. Are these combinations possible? L3VPN + OSPF point-to-point : same AS L3VPN + OSPF point-to-point : different AS L2VPN + OSPF point-to-point : same AS L2VPN + OSPF point-to-point : different AS Pls…
