Re: OSPF neighbour-ship on multi-ip P2P interface
by Santosh P K 09 Jan '20

In case of unnumbered I do not think we can work with multiple IP address for OSPF. Simply because fetching right OSPF interface would not be possible when multiple IP address configured. Thanks Santosh P K From: Naveen K Suvarna <naveen.suvarna(a)broadcom.com> Date: Thursday, 9 January 2020 at 6:23 PM To: Santosh P K <sapk(a)vmware.com>, "dev(a)lists.frrouting.org" <dev(a)lists.frrouting.org> Subject: Re: OSPF neighbour-ship on multi-ip P2P interface Hi Santosh, Thanks a lot for the analysis. My base software does not allow me to configure non /32 ip addresses. Hence I had configured two non /32 ip addresses on same interface and sessions came up for both IP addresses. Interface was considered as regular interface rather than unnumbered interface. In case of session flap with unnumbered interface dual IP, Can we consider it as an expected behaviour or there is room for fix ? Regards Naveen From: Santosh P K <sapk(a)vmware.com> Date: Thursday, 9 January 2020 at 2:39 PM To: Naveen K Suvarna <naveen.suvarna(a)broadcom.com>, "dev(a)lists.frrouting.org" <dev(a)lists.frrouting.org> Subject: Re: OSPF neighbour-ship on multi-ip P2P interface Naveen, The issue is with unnumbered interface. With this you see flap only when multiple interface address is configured even if prefix is no /32. I tried with /31 and /24 as well but I still see flaps. Not sure how it worked for you. The reason for flap is due to the code below. Sending hello: There are two ospf interface created when you have multiple IP address. Hello will be sent on both with each IP address as the source address in it and rest of the hello content remains the same. Receiving hello: When hello is received then OSPF tries to get the OSPF interface. In case of unnumbered it gets the first ospf interface on that IFP. As in case of unnumbered there is no way we can match on prefix as received source may not have any overlapping IP address with what is configured as source. In function ospf_if_lookup_recv_if which is called by ospf_read to get the ospf interface. if (CHECK_FLAG(oi->connected->flags, ZEBRA_IFA_UNNUMBERED)) match = oi; >>>>> Gets the fist OI and uses that. else if (prefix_match(CONNECTED_PREFIX(oi->connected), (struct prefix *)&addr)) { if ((match == NULL) || (match->address->prefixlen < oi->address->prefixlen)) match = oi; } Flap: Flap is caused due to receiving two hellos from peer and mapping to only single ospf interface. Now take the case where you have two IP address configured on the same interface on either end (R1- 10.10.10.1, 20.20.20.1 and R2- 10.10.10.2, 20.20.20.2). When Router R1 sends hello with source IP in IP header as 10.10.10.1 to R2 then it receives it and matches with first ospf interface let’s assume that is associated with IP 10.10.10.2. When R1 sends hello with source IP in IP header as 20.20.20.1 then R2 will still map to 10.10.10.2 ospf interface as that is first in list. R2 will keep receiving hello from R1 one with neighbour seen and other without it and hence we see OSPF session flapping.

Sessions do come up in /31 prefix. I am using version 7.2. I have a loopback interface with multiple /32 prefix IPs assigned. This loopback is borrowed by an unnumbered OSPF interface. Two node, directly connected single link ospf topology, as give below. When only one IP is present in the loopback interface, sessions comes up. If more than one Ip is added to the loopback interface, ospf session keep getting flap/reset. Difference I see between /32 and / <1-31> Prefix is that, in hello packet network mask is set to 0 in case of /32.

I am using multiple 32bit host ip address on same interface. When I try to establish ospf neighborship on an P2P interface with multiple IP addresses assigned, OSPF neighborship keeps resetting due to, receival of interleaving hello of 1st or 2nd ip-address. Is there any way to avoid this and bring up sessions on the Interface. Above thing works good if the Interface IP addresses are assigned < 32 bit subnet mask (for example, 10.0.0.1/24 instead of 10.0.0.1/32). Regards Naveen
