Which four statements are correct regarding MSDP configurations and operations? (Choose four.)
A.The MSDP peers are also typically the RPs in respective routing domains.
B.SA messages are flooded to all other MSDP peers without any restrictions
C.On Cisco IOS, IOS-XE, and IOS-XR, the router can be configured to cache the SA messages to reduce the join latency
D.SA messages are used to advertise active sources in a domain
E.MSDP establishes neighbor relationships with other MSDP peers using TCP port 639
F.MSDP peerings on Cisco IOS, IOS-XE, and IOS-XR support MD5 or SHA1 authentication
Which two specific characteristics categorize traceroute in an IPv6 routing environment? (Choose two.)
A.Traceroute can show the path to reach any destination IPv6 address.
B.Traceroute returns an error for a link-local IPv6 address.
C.Traceroute is based on ICMPv6 Type 1 (Destination Unreachable) reply packets to determine the network path.
D.Traceroute is based on ICMPv6 Type 3 (Time Exceeded) reply packets to determine the network path.
E.Traceroute is based on ICMPv6 Type 2 (Packet Too Big) reply packets to determine the network path.
F.Traceroute for IPv6 implements a backwards compatibility option to provide a detailed report in environments running dual-stack.

Which four operations are components of MSDP in interdomain multicast setup? (Choose four.)
A.Multiple domains can have a single statically defined RP.
B.RPs interconnect between domains with UDP connections to pass source active
C.RPs interconnect between domains with TCP connections to pass source active
D.RPs send source active messages for internal sources to MSDP peers.
E.Source active messages are Peer-RPF checked before accepting or forwarding.
