How to debug IPV6

[D'Arcy Cain <darcy%NetBSD.org@localhost>]

I thought that I had everything set up properly but it doesn't
communicate.  Here are two interfaces on the same network.

wm0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
   capabilities=7ff80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx>
   capabilities=7ff80<TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx,TCP6CSUM_Rx>
   capabilities=7ff80<TCP6CSUM_Tx,UDP6CSUM_Rx,UDP6CSUM_Tx,TSO6>
   enabled=0
   ec_capabilities=3<VLAN_MTU,VLAN_HWTAGGING>
   ec_enabled=0
   address: 00:30:48:8f:76:08
   media: Ethernet autoselect (100baseTX full-duplex)
   status: active
   inet 98.158.139.93 netmask 0xffffffe0 broadcast 98.158.139.95
   inet6 fe80::230:48ff:fe8f:7608%wm0 prefixlen 64 scopeid 0x1
   inet6 2605:2600:1001::5d prefixlen 64
   inet6 2605:2600:1::5 prefixlen 127

bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
   capabilities=3f00<IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx>
   capabilities=3f00<UDP4CSUM_Rx,UDP4CSUM_Tx>
   enabled=0
   ec_capabilities=3<VLAN_MTU,VLAN_HWTAGGING>
   ec_enabled=0
   address: 00:21:9b:fc:c5:cc
   media: Ethernet autoselect (100baseTX full-duplex)
   status: active
   inet 98.158.139.67 netmask 0xffffffe0 broadcast 98.158.139.95
   inet6 fe80::221:9bff:fefc:c5cc%bge0 prefixlen 64 scopeid 0x1
   inet6 2605:2600:1001::43 prefixlen 64

But from the first host:

$ traceroute6 2605:2600:1001::43
traceroute6 to 2605:2600:1001::43 (2605:2600:1001::43) from
2605:2600:1001::5d, 64 hops max, 12 byte packets
 1  2605:2600:1001::5d  2998.21 ms !H  3001.04 ms !H  3008.02 ms !H

Trying "ping6 -nd 2605:2600:1001::43" didn't work either.

I am sure that I must be missing something obvious but I can't figure
out what.
