Local anycast address not added to ospf table
I've been following this guide https://www.linuxjournal.com/magazine/ipv4-anycast-linux-and-quagga on setting up Quagga/OSPFd for anycast. However the anycast address is never sent out via ospf nor added to the ospf route table.


Logs show

2018/05/15 01:07:46 OSPF: Redistribute[connected]: 10.10.20.5/32 already exists, discard.
2018/05/15 01:07:46 OSPF: ospf_zebra_read_ipv4() : 10.10.20.5 already exists

I've found the same issue reported to the RedHat Bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1441882 however this was closed as not a bug with no comments.

OS is RHEL7


Any help or suggestions on where to go from here? I've searched the lists and couldn't find anything matching this.

Re: Local anycast address not added to ospf table [ In reply to ]
Hi,

What version of quagga are you running ? ( that could help )
Also, is it possible to share your config ? both from the zebra/ospf
config but also the linux network config if you find it relevant.

let's start from there :)

Regards,
Nico
