Re: OSPFv3 Neighbor Stuck in EXSTART/EXCHANGE

We have the our session in IPv4 functions correctly between these 2
devices. I'm not sure that the problem related to the LAG.

Network type: Broadcast between 2 devices:

The quagga device:
eth1_0.135 is up, type BROADCAST
   Interface ID: 13
   Internet Address:
     inet : 194.145.54.57/28
     inet6: 2a03:b00:0:135::57/96
     inet6: fe80::2e0:edff:fe1b:242d/64
   Instance ID 0, Interface MTU 1500 (autodetect: 1500)
   Area ID 0.0.0.1, Cost 1
   State DR, Transmit Delay 1 sec, Priority 1
   Timer intervals configured:
    Hello 10, Dead 40, Retransmit 5
   DR: 194.145.54.61 BDR: 194.145.54.2
   Number of I/F scoped LSAs is 1

interface eth1_0.135
  ipv6 nd suppress-ra
  ipv6 ospf6 cost 1
  ipv6 ospf6 dead-interval 40
  ipv6 ospf6 hello-interval 10
  ipv6 ospf6 instance-id 0
  ipv6 ospf6 priority 1
  ipv6 ospf6 retransmit-interval 5
  ipv6 ospf6 transmit-delay 1

router ospf6
  router-id 194.145.54.61
  interface eth1_0.135 area 0.0.0.1

Cisco 6k5:
interface Port-channel3

  ip address 194.145.54.53 255.255.255.240
  ipv6 address 2A03:B00:0:135::53/96
  ipv6 ospf 1 area 1

sh ipv os int po3
Port-channel3 is up, line protocol is up (connected)
   Link Local Address FE80::226:99FF:FE64:1D40, Interface ID 160
   Area 1, Process ID 1, Instance ID 0, Router ID 194.145.54.2
   Network Type BROADCAST, Cost: 1
   Transmit Delay is 1 sec, State BDR, Priority 1
   Designated Router (ID) 194.145.54.61, local address

   Backup Designated router (ID) 194.145.54.2, local address

   Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
     Hello due in 00:00:07
   Index 1/1/3, flood queue length 0
   Next 0x0(0)/0x0(0)/0x0(0)
   Last flood scan length is 12, maximum is 12
   Last flood scan time is 0 msec, maximum is 0 msec
   Neighbor Count is 1, Adjacent neighbor count is 0
   Suppress hello for 0 neighbor(s)

Thanks,
