* pimd: Abstract a RPF change for upstream handlingDonald Sharp2018-08-011-0/+3
| | | | | | | Abstract the RPF change for upstream handling code so that we do not have two copies of the code. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* pimd: Abstract sending of data to peersDonald Sharp2018-07-311-0/+2
| | | | | | | After we have decided what has changed as part of a update we need to send the j/p messages to our peers. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* pimd: make igmp_source_forward_reevaluate_all vrf awareDonald Sharp2018-03-181-1/+1
| | | | | | | | There is no need to look at all VRF's when we need to reevaluate the source forward since the calling function knows the vrf. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* pimd: Make the rpf scan per vrf.Donald Sharp2018-03-181-1/+1
| | | | | | | | | We know the vrf that we are in when we need to initiate a rescan of the rpf cache. So pass it in and use that information. This should help the rescan at scale with several vrf's cutting out a lot of unnecessary work. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* pimd: Allow installation of NULL mroute in some situationsDonald Sharp2017-07-241-1/+1
| | | | | | | | | When we receive a S,G,RPT prune as part of a *,G tree, install the NULL oil S,G mroute. This will cause the traffic to stop flowing for this particular S,G as we expect. Ticket: CM-16978 Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* *: make consistent & update GPLv2 file headersDavid Lamparter2017-05-151-18/+17
| | | | | | | | | | | The FSF's address changed, and we had a mixture of comment styles for the GPL file header. (The style with * at the beginning won out with 580 to 141 in existing files.) Note: I've intentionally left intact other "variations" of the copyright header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

* pimd: Allow SSM groups to co-exist with ASM groups.anuradhak2017-03-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SSM groups (232/8 or user configured SSM range) can exist in the same multicast network as ASM groups. For such groups all RPT related state machine operations have to be skipped as defined by section 4.8 of RFC4601 - 1. Source registration is skipped for SSM groups. For SSM groups mroute is setup on the FHR when a new multicast flow is rxed; however source registration (i.e. pimreg join) is skipped. This will let the ASIC black hole the traffic till a valid OIL is added to the mroute. 2. (*,G) IGMP registrations are ignored for SSM groups. Sample output: ============= fhr# sh ip pim group-type SSM group range : 232.0.0.0/8 fhr# sh ip pim group-type 232.1.1.1 Group type: SSM fhr# sh ip pim group-type 239.1.1.1 Group type: ASM fhr# Sample config: ============= fhr(config)# ip pim ssm prefix-list ssm-ranges fhr(config)# Signed-off-by: Anuradha Karuppiah <anuradhak@cumulusnetworks.com> Reviewed-by: Donald Sharp <sharpd@cumulusnetworks.com> Ticket: CM-15344 Testing Done: 1. SSM/ASM source-registration/igmp-joins. 2. On the fly multicast group type changes. 3. pim-smoke.
* pimd: Nexthop tracking supportChirag Shah2017-03-161-1/+5
| | | | | | | | | | | | | Add pim Nexthop tracking feature 1st part where, specific RP or Source address (unicast address) register with Zebra. Once nexthop update received from Zebra for a given address, scan RP or upstream entries impacted by the change in nexthop. Reviewed By: CCR-5761, Donald Sharp <sharpd@cumulusnetworks.com> Testing Done: Tested with multiple RPs and multiple *,G entries at LHR. Add new Nexthop or remove one of the link towards RP and verify RP and upstream nexthop update. similar test done at RP with multiple S,G entries to reach source.

* *: add frr_config_fork()David Lamparter2017-03-081-1/+1
| | | | | | | | | Centralise read_config/daemonize/dryrun/pidfile/vty_serv into libfrr. This also makes multi-instance pid/config handling available as part of the library. It's only wired up in ospfd, but the code is in lib/. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>

* | pim-nexthop: mroute and pim-upstream rpf are falling out of sync.anuradhak2016-12-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the mroute-IIF and upstream RPF-IIF/neigh are resolved separately. This must change i.e. be merged together for a couple of reasons - 1. In the case of ECMP we will use a load-share mechanism (based on G or SG) to pick an RPF neighbor in 3.2.1 (to use the load-sharing cap of anycast-RP). Using a different resolution mechanism for mroute-IIF will simply not work. 2. In a non-CLOS topology it is actually possible to have routers that do not participate in PIM. In this case the tree will be set up using different routers than the ones chosen for the mroute IIF. And traffic will not be forwarded. This change is however too big for 3.2.0. So to handle CM-13714 I have simply forced rpf update on neigh add which fixes the specific problem seen on link flap in a clos (it is not very efficient but traffic recovers).

* pimd: merge pimd as of 2015-01-19David Lamparter2016-05-261-0/+42
Welcome pimd to the Quagga daemon zoo! This is a merge of commit 77ae369 ("pimd: Log ifindex found for an interface when zebra lib reports a new connected address."), with the intermediate "reconnect" changes removed (c9adf00...d274381). d274381 is replaced with b162ab7, which includes some changes. In addition, 4 reconnect-related changes and 1 cosmetic one have been bumped out. The rebase command used to produce the branch that is merged here is: git rebase --onto b162ab7 c9adf00 77ae369 Note that 3 patches had their author rewritten from "Anonymous SR#108542 <>" (which is not a valid git author ID) to: "Savannah SR#108542 <nbahr@atcorp.com>" (which is the e-mail address listed in the associated Savannah ticket) Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
