Hi,
I have a Linux server and a Cisco IOS XE device connected with GRE/IPSec and
then can ping each other. Today I installed Bird 2.0.5 on the Linux server and
enabled OSPFv2 on both of them. Although they receive HELLO packets from each
other, they refuse to establish a connection. A packet capture shows Bird is
sending packets with auth type = 256 which is not something I would expect
everyday:
05:38:06.129722 IP (tos 0xc0, ttl 1, id 48901, offset 0, flags [none], proto
OSPF (89), length 64)
192.168.1.2 > ospf-all.mcast.net: OSPFv2, Hello, length 44
Router-ID 192.168.1.2, Backbone Area, Authentication Type: unknown (256)
As a test I changed authentication type from none to simple; this time Bird
gave me 257:
05:40:36.129411 IP (tos 0xc0, ttl 1, id 3669, offset 0, flags [none], proto
OSPF (89), length 64)
192.168.1.2 > ospf-all.mcast.net: OSPFv2, Hello, length 44
Router-ID 192.168.1.2, Backbone Area, Authentication Type: unknown (257)
Is there something wrong with my config or there is a bug in Bird2? Is there
any workaround I can use right now?
I've already checked on both sides their interface type is set to ptp and all
timers match.
My environment:
* Cisco IOS XE 16.9.3, CSR1000v in Hyper-V VM
* Debian 10 in KVM, Bird 2.0.5 via official unstable repo, IPSec done with
strongswan
Thanks ahead,
James Swineson
