1) It has higher priority than BSR, even more if BSR knows about AuroRP, it
starts send AutoRP value not rp-candidate value.
AutoRP multicasts RP mappings on 224.0.1.40, while BSR uses 224.0.0.13. All
pim routers join 224.0.1.40 if pim-sparse-dense mode is enabled, and will
therefore receive AutoRP mappings, as well as bsr rp-sets. If the two
conflict for a particular group address, I'm not sure how that is resolved.
Probably need to lab it up.
However, if only pim-sm is enabled, i believe only the bsr rp-set will be
used to select an rp.
2) AutoRP listener could not be disabled on cisco router.
I'm not aware of a command to specifically disable receiving autorp
mutlicasts, short of acl filtering 224.0.1.40, or configuring pim-sm.
3) AutoRP can not be filtered with ip pim bsr border
true
4) AutoRP can to be filtered with ip pim rp-announce-filter on non mapping
agent routeres
5) It can be filtered only with
ip multicast boundary ACL filter-autorp
or with interface ACL.
correct
PS: Is "ip multicast boundary ACL filter-autorp" affect other (non autorp)
multicast traffic?
use the acl to specify non autorp group addresses to filter
