There was a network outage today, and I got so hung up on this fact that it distracted me from the real problem... Now that the network is back up, I want to know why I cannot ping my default gateway.
There are several networks running on this switch.
All virtual interfaces are up/up.
Ip addressing is correct, with the correct subnet mask.
CompA on VLAN A can ping it's default gateway, CompB on VLAN B cannot. Both computers are directly connected to the L3 switch.
If I ping from compA with debug ICMP on, I see the echo replies.
If I ping with CompB, I do not see echo replies. If I tracert to a distant network, I see the TTL expired message on the default gateway and it works fine getting to the end device. If I run tracert to my default gateway, I see the echo reply.
There are no ACL's on the switch. No windows firewall issues, as I am able to ping distant end routers just fine, just not my default gateway.
ARP entries are also present and correct on all devices.
