Limitations
The limitations of MSDP (Multicast Source Discovery Protocol) are as
follows:
- There is no support for MSDP operating with SA cache disabled
(transit node). MSDP will always cache/store received SA messages.
- There is no support for logical RP.
- There is no support for MSDP on user-created virtual routers
(VRs).
- RIP (Routing Information Protocol) routes are not used for
peer-RPF checking. So, our implementation of MSDP does not exactly conform to rule
(iii) in section 10.1.3 of RFC 3618. However, our implementation of MSDP uses
BGP (Border Gateway Protocol)/OSPF (Open Shortest Path First) for peer-RPF checking as per
rule (iii) in section 10.1.3.
- Read-write/read-create access is not supported on MSDP MIB
objects.
