Policy Route And Route Policy - Zte ZXR10 ZSR V2 Series Product Description

3.1.2.6 MSDP
Multicast Source Discovery Protocol (MSDP) is a mechanism connecting several PIM
domains. It works on TCP to provide PIM-SM with multicast source information outside
PIM domain.
A MSDP speaker in one PIM-SM domain creates a session with other inter-domain MSDP
neighbors via TCP. When the MSDP speaker knows a new multicast source in the MSDP
domain (through the PIM register mechanism), it generates a Source Active (SA)
message and sends it to all MSDP neighbors.

Policy route and route policy

3.1.3.1 Policy routing
ZXR10 ZSR V2 supports policy routing to forward packets according to the policy
designated by a user. The policy routing provides the packet forwarding policy, and match
object is packet. Match objects is screened according to attribute fields and the set action
is designated. The set is divided into two types: One is route option which changes a
forwarding path, and the other is packet modification option which modifies the attributes
of the screened packet. Policy routing implements traffic engineering to a certain extent,
thus flows of different QoS or data of different types (such as voice and FTP) can take
different paths.
3.1.3.2 Route policy
Route policy is the route distributing and receiving policy. Route protocol selection is
actually a route policy. Route policy means modifying parameters or setting control mode
to change the results of route creation, distribution and selection. ZXR10 ZSR V2
supports RIP, OSPF, IS-IS, BGP and VRF to use route policy.



