Hello Testing babeld config with 6.0.2 FRR on CentOS 7 The problem is I dont see any neighbor on sh babel neighbor command, I can see the traffic with tcpdump on eth1..adn also i can ping the opposite server without a problem. I have two virtual servers having 4 interfaces.. eth0 is access port tesing babeld with eth1 and eth3 interfaces. Am I missing anything? *********************************** First server frr config; interface eth1 babel hello-interval 300 babel update-interval 100 babel wired ip address 192.168.100.1/24 ! router babel network eth1 redistribute ipv4 kernel redistribute ipv4 static redistribute ipv4 connected ! ----------- Second server: interface eth1 babel hello-interval 300 babel update-interval 100 babel wired ip address 192.168.100.2/24 ! interface eth3 ip address 192.168.254.2/24 ! router babel network eth1 network eth3 redistribute ipv4 kernel redistribute ipv4 static redistribute ipv4 connected My ip route outputs; 1st server: C>* 10.1.1.0/24 is directly connected, eth0, 00:11:59 C>* 192.168.100.0/24 is directly connected, eth1, 00:11:59 C>* 192.168.200.0/24 is directly connected, eth2, 00:11:59 Second Server: K>* 0.0.0.0/0 [0/100] via 10.1.1.1, eth0, 00:16:35 C>* 10.1.1.0/24 is directly connected, eth0, 00:16:35 C>* 192.168.100.0/24 is directly connected, eth1, 00:16:35 C>* 192.168.200.0/24 is directly connected, eth2, 00:16:35 C>* 192.168.254.0/24 is directly connected, eth3, 00:16:35 and centos1# *sh babel route * 0.0.0.0/0 metric 0 (exported) 10.1.1.0/24 metric 0 (exported) 192.168.100.0/24 metric 0 (exported) 192.168.200.0/24 metric 0 (exported) centos1# centos1# centos1# centos1# centos1# centos1# sh babel route 0.0.0.0/0 metric 0 (exported) 10.1.1.0/24 metric 0 (exported) 192.168.100.0/24 metric 0 (exported) 192.168.200.0/24 metric 0 (exported) centos1# *sh babel neighbor* centos1#* sh babel parameters * -- Babel running configuration -- state file = /var/run/frr/babel-state configuration file = /etc/frr/babeld.conf protocol information: multicast address = ff02::1:6 port = 6696 vty address = None vty port = 2609 id = 3e:13:48:ff:fe:39:a2:d3 kernel_metric = 0 -- distribution lists -- Outgoing update filter list for all interface is not set Incoming update filter list for all interface is not set
