simple frr ospf example setup
by Moritz Warning 23 Aug '20

23 Aug '20

Hi, I am a newbie with frr/ospf. My aim is to run two ospfd instances in a Linux network namesspace each and let them talk to each other via a virtual link (interface called uplink). My test setup is attached. But I do not see any traffic. This is probably some basic configuration error. I did have a look at the documentation, but it did not seem to cover such simple setups. A few pointer in the right direction would be helpful. thanks, mwarning $ ip netns add ns-0 $ ip netns add ns-1 # Node 0: $ sudo ip netns exec ns-0 ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 4: uplink@if3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether ce:e6:b3:5d:d3:70 brd ff:ff:ff:ff:ff:ff link-netns switch inet 192.168.1.0/24 scope global uplink valid_lft forever preferred_lft forever inet6 fe80::cce6:b3ff:fe5d:d370/64 scope link valid_lft forever preferred_lft forever $ cat ospf0.conf router ospf ospf router-id 192.168.1.0 network 192.168.1.0/24 area 1 $ sudo ip netns exec ns-0 ospfd --terminal -f ./ospf0.conf -i /run/frr/ospfd0.pid # Node 1: $ sudo ip netns exec ns-1 ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 7: uplink@if6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 12:45:ca:46:19:52 brd ff:ff:ff:ff:ff:ff link-netns switch inet 192.168.1.1/24 scope global uplink valid_lft forever preferred_lft forever inet6 fe80::1045:caff:fe46:1952/64 scope link valid_lft forever preferred_lft forever $ cat ospf1.conf router ospf ospf router-id 192.168.1.1 network 192.168.1.0/24 area $ sudo ip netns exec ns-1 ospfd --terminal -f ./ospf1.conf -i /run/frr/ospfd1.pid

EIGRP not working in 7.3/7.4 releases
by Amol Lad 10 Aug '20

10 Aug '20

Hi, First, thank you for integrating FRR in OpenWrt. I used the latest FRR package in OpenWrt (which is FRR 7.4 release). I'm trying to configure EIGRP but it seems the "network" command is not configuring the correct network. For example, see below steps. I'm configuring "network 172.16.1.0/24" under eigrp but the running config shows "network 255.255.255.0/24" I'm not sure if this is OpenWrt specific issue or a general issue and I'll try release 7.3/7.4 on Ubuntu tomorrow. But please let me know if you latest FRR release and can successfully configure EIGRP. Thanks Amol root@arm-linux:/# vtysh Hello, this is FRRouting (version 7.4).
