This is an important optimization for users running FRR on systems with

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.

On the FHR upstream-join-state is not particularly relevant as we
don't need to send upstream JPs for the SG. So that field was being
overloaded with the register-state. However some of the events that
triggered changes to the JoinDesired macro were accidentally overwriting
the state with join info (instead of treating it as register info)
confusing the register state machine.
To make the PIM RFC macros' implemention simple I have separated out
the register-state. And upstream->state now solely describes the

Anycast rp requires multiple ip addresses on the lo. If PIM is used in
an unnumbered BGP network it picks one of the lo addresses as the
pim-primary for the swp interfaces. But if the anycast IP is picked up
by both sides pim nbr will never converge. So a static "use-source" config
is provided to allow the administrator to force the the hello source to the
unique IP address.

Anycast requires that the lo interface be associated with multiple
addresses. One is the anycast IP address (which is the same on all RPs
participating in RP redundancy) and the second is the unique IP address
that will be used as the router id by routing protocols.
To accomodate that we maintain a list of secondary addresses per-pim iface
and allow any of them to be the RP address. This lets the I_am_RP macro
succeed on anycast RPs.
Note that the support is limited i.e. we don't actually advertise a
secondary list to the neighbors. This is assuming the anycast IP will never
be used as a router id i.e. will never be an RPF neighbor.

activity is detected the keepalive timer is started and SPT bit set.
A SRC_STREAM reference is also created for the entry if one doesn't
already exist.
3. If KAT actually expires it means the flow is no longer active. At
this point we stop advertising the SA to MSDP peers. We also pull

references).

1. Add support for mesh-group based configuration that is easy to apply
via automation. The older per-peer configuartion is temporarily hidden
and will be cleaned up later.
Sample config -
ip msdp mesh-group cumulus source 100.1.1.4
ip msdp mesh-group cumulus member 100.1.1.5
ip msdp mesh-group cumulus member 100.1.1.6
2. Added support for detail peer and sa-cache displays. Along with
filter keys.
3. Add json output for all the msdp displays.
With this commit basic support for anycast-RP with MSDP (in numbered
network is complete). Unnumbered support will be added separately.

1. Added a new MSDP source reference flag for creating (S,G) entries
based on the SA-cache. The RFC recommends treating as SA like rxing
a (S, G) join (which is a bit different then treating like a traffic
stream).
2. SA-SPT is only setup if we are RP for the group and a corresponding
(*,G) exists with a non-empty OIL.
3. When an SA is moved we need to let the SPT live if it is active (this
change will come in a subsequent CL).
Testing done:
1. SA first; SPT setup whenever (*, G) comes around.
2. (*, G) first. As soon as SA is added SPT is setup.
3. (*, G) del with valid SA entries around.

When we have multiple incoming joins for
a single group on a interface, we need to
allow proper output.

If you add to the json by grp, if you have multiple
ifchannels for that group, on the the first one will
be displayed.

This commit includes -
1. Maintaining SA cache with local and remote entries.
2. Local SA entries - there are two cases where we pick up these -
- We are RP and got a source-register from the FHR.
- We are RP and FHR and learnt a new directly connected source on a
DR interface.
3. Local entries are pushed to peers immediately on addition and
periodically. An immediate push is also done when peer session is
established.
4. Remote SA entries - from other peers in the mesh group and passed
peer-RPF checks.
5. Remote entries are aged out. No other way to del them
currently. In the future we may add a knob to flush entries on
peer-down.
Testing done -
Misc topologies with CL routers plus basic interop with another vendor (
we can process their SA updates and they ours).
Sample output -

This fix handles two issues:
1) Searching entire vrf_iflist to get per interface pim_ifchannel_list
2) Display of ifchannel information in pim not being ordered correctly.

This commit includes the following changes -
1. Support for MSDP peer DB (hash and sorted list).
2. Support for the following timers - keepalive, connect-retry, hold.
3. TCP session management (lower-ip is active, higher-ip is passive).
4. MSDP KA packet rx/tx.
5. Limited temporary config (will be replaced with the more automation
friendly RP-set).
Testing done -
Peer bringup/deletion (including interop with another vendor)

The test commands are not being maintained and
are not out of date with the rest of the system. There
are better ways to test code and in addition these
commands if entered by a user could seriously impact
their running system.

This cleans up the following so that they always collect the data to
display in json structures and then either dumps the json output or
traverses it to produce the non-json output.
