Hello,
We run BFD on all of our devices and we're currently having some
problems between a pair of C6500/SUP720 and a ME3600X .
The network diagram is as follows:
+-----------+
| |
+--------+ C6500_1 |
| | |
| +----+-+----+
+----+----+ | |
| | | |
| ME3600X | | |
| | | |
+----+----+ | |
| +----+-+----+
| | |
+--------+ C6500_2 |
| |
+-----------+
Both the C6500 run the following software:
s72033-adventerprisek9-mz.151-2.SY2.bin
Both C6500 are SUP720-3B and there isn't any dCEF enabled card on them.
The OSPF sessions on C6500_1 is in FULL state:
C6500_1# show ip ospf neighbor | i 2/7
192.0.2.19 0 FULL/ - 00:00:32 192.0.2.173 GigabitEthernet2/7
and the relevant configuration is as follows:
interface gigabitEthernet 2/7
ip ospf network point-to-point
ip ospf 1 area 0
bfd interval 300 min_rx 300 multiplier 3
no bfd echo
!
router ospf 1
bfd all-interfaces
!
Anyway IOS is not able to start a BFD session on that interface:
C6500_1# show ip ospf neighbor 212.183.160.19 | i BFD
C6500_1#
And returns an error when BFD debugging is on:
C6500_1#show debugging
BFD:
BFD event debugging is on for interface GigabitEthernet2/7
BFD packet debugging is on for interface GigabitEthernet2/7
C6500_1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
C6500_1(config)#int gi2/7
C6500_1(config-if)#no bfd interval
C6500_1(config-if)#bfd interval 300 min_rx 300 multi 3
C6500_1(config-if)#
Dec 9 16:07:42.737: BFD-DEBUG EVENT: bfd_session_create failed, 6
C6500_1(config-if)#
At the same time there are running BFD sessions on other interfaces
configured with the very same statements:
For instance the following interface is connected to another ME3600X
that is running the same software version:
C6500_1#show bfd neighbors | i 2/6
192.0.2.109 294/3 Up Up Gi2/6
C6500_1#
Can anyone help?
Thank You
