I have a weird issue and I need some help.
I have two ICX6450 switches connected to each other.
SW1 has VLAN1 on 10.1.0.0/24 and SW2 has VLAN1 on 10.2.0.0/24.
Both switches are connected via VLAN1012 on 10.1.2.0/24.
Both switches have ve's on VLAN1012 and VLAN1.
Both switches have static routes configured for each other's VLAN1 subnet via their "partner's" VLAN1012 ve. I will post the config below.
I am trying to route from SW1 VLAN1 to SW2 VLAN2. Using a host on SW1, I can ping some hosts on SW2 but not others. Traceroute does not help at all. The host is configured with a static IP and the SW1 VLAN1 ve IP as its gateway for this troubleshooting session.

traceroute to a second unreachable SW2 host from SW1 host:
Code:
$ traceroute 10.2.0.4
traceroute to 10.2.0.4 (10.2.0.4), 30 hops max, 60 byte packets
1 _gateway (10.1.0.2) 7.037 ms 7.712 ms 8.369 ms
2 10.1.2.241 (10.1.2.241) 5.443 ms 5.417 ms 5.392 ms
3 10.1.2.116 (10.1.2.116) 6.600 ms 6.576 ms 6.550 ms
This last one is particularly confusing to me because 10.1.2.116 is a pfSense interface on VLAN1012 at SW2 location. Why is the SW2 trying to forward the packet to the pfSense interface instead of the actual host at 10.2.0.4?
Please help!
