I recently got 2 connections from 2 different ISPs and thought to remove eth1 from the bridge and use it as a 2nd WAN port.īoth of my ISPs provided static IPs for router configuration. eth1 and wlan0 are bridged together ( br-lan). It has 3 interfaces: eth0 (single WAN port), eth1 (single LAN port), and wlan0 (WIFI). Round-trip min/avg/max = 0/0/0 msSo something strange is happening with the nexthop address.Ġ0:04:96:98:87:01 is the switch MAC address of rx1, so that link-local nexthop looks sensible.I am using GLinet AR-150. ![]() If I configure a static route across the link, I can ping loopback to loopback: Ping(ICMP6) 2001:xxxx::79: 4 packets, 8 data bytes, interval 1 second(s).Ĥ packets transmitted, 0 packets received, 100% loss However, if I configure static routes, it *does* make it to the FIB: No, the OSPFv3 route isn't making it to the FIB. Has anyone else seen anything similar? I'm running 21.1.3.7 on these X460s. I'm in the process of trying to reproduce in the lab on a much simpler config (in theory, this can be done with two X460 G2s with two VRFs and one point to point link). This is a key point, it seems that the forwarding inside the VR is the problem and not OSPFv3 in general. If I work in VR-Default on these switches, and configure some IPv6 between RX1 and RX2, things work as expected. If you break the link between RX2 and Cisco 2 (or Cisco 2 goes away):Ģ) You can ping RX1's loopback (and everything else in the network) from RX2 on IPv4.ģ) OSPFv3 still shows adjacencies are up between RX1 and RX2.Ĥ) On RX2, the IPv6 next-hop for RX1's loopback remains the same, the directly connected link to RX1 as expected.ĥ) However, you cannot ping RX1's loopback from RX2 on IPv6.Ħ) Nor can you ping Cisco 1's loopback from RX2 on IPv6.ħ) Unsurprisingly, given (5) and (6) above, iBGP goes down. ![]() iBGP all up.Ĥ) On RX2, the IPv6 next-hop for RX1's loopback is via the link directly to RX1 as expected. ![]() Some troubleshooting later and it seems that the following case is true if all links are up:Ģ) You can ping RX1's loopback from RX2, v4 and v6.ģ) OSPFv3 shows adjacencies all up. Happy little routing networkĮxcept that recently we had a failure of Cisco 2 - and I noticed that the IPv6 iBGP sessions between RX2 and RX1, and between RX2 and Cisco 1 went down. These all run OSPF, OSPFv3 and iBGP between them. On each physical link, there is a point-to-point VLAN in a user VR, 'VR-Internet', with v4 and v6 addresses. Somewhat simplifying, I have four devices physically connected like this: ![]() Before I open a TAC case about this, I'm just trying to find out if anyone else is doing something similar and has the same issue.
