Verifying the Configuration of SA Message Parameters

Verifying the Configuration of SA Message Parameters

After configuring source active (SA) message parameters, verify information about and the number of (S, G) entries in the SA cache and check details about MSDP peers.

Prerequisites

SA message parameters have been configured.

Procedure

  • Run the display msdp [ vpn-instance vpn-instance-name | all-instance ] sa-cache [ group-address | source-address | { as-number-plain | as-number-dot } ] * command to check information about (S, G) entries in the SA cache.
  • Run the display msdp [ vpn-instance vpn-instance-name | all-instance ] sa-count [ as-number-plain | as-number-dot ] command to check the number of (S, G) entries in the SA cache.
  • Run the display msdp [ vpn-instance vpn-instance-name | all-instance ] peer-status [ peer-address ] command to check detailed information about MSDP peers.

Example

Run the display msdp sa-cache command. The command output shows information about the (S, G) entries in the SA cache.

<HUAWEI> display msdp sa-cache
MSDP Source-Active Cache Information of VPN-Instance: public net
 MSDP Total Source-Active Cache - 2 entries
 MSDP matched 2 entries

(10.0.5.120, 225.0.0.1)
 Origin RP: 3.3.3.3
 Pro: ?, AS: ?
 Uptime: 00:01:01, Expires: 00:05:59

(10.0.5.120, 225.0.0.2)
 Origin RP: 3.3.3.3
 Pro: ?, AS: ?
 Uptime: 00:00:01, Expires: 00:05:59

Run the display msdp sa-count command. The command output shows the number of (S, G) entries in the SA cache. The entries are counted based on the numbers of the autonomous systems (ASs) where MSDP peers and Rendezvous Points (RPs) reside.

<HUAWEI> display msdp sa-count
MSDP Source-Active Count Information of VPN-Instance: public net
Number of cached Source-Active entries, counted by Peer
  Peer's Address     Number of SA
  10.10.10.10        5
Number of source and group, counted by AS
  AS     Number of source    Number of group
  ?      3                      3
  Total 5 Source-Active entries matched 

Run the display msdp peer-status [ peer-address ] command. The command output shows detailed information about a specified or all MSDP remote peers.

  • The SA-cache maximum for the peer field displays the maximum number of (S, G) entries in the SA cache.

  • The Information about SA-Requests field displays the configuration of SA Request messages.

  • The Minimum TTL to forward SA with encapsulated data field displays the TTL threshold for SA messages that contain multicast data packets.

  • The Information about (Source, Group)-based SA filtering policy field displays the policies for filtering SA messages.

For example:

<HUAWEI> display msdp peer-status 10.110.11.11
MSDP Peer Information of VPN-Instance: public net
MSDP Peer 1.1.1.1, AS 100
  Description:
  Information about connection status:
    State: Up
    Up/down time: 14:41:08
    Resets: 0
    Connection interface: LoopBack0 (1.1.1.3)
    Number of sent/received messages: 867/947
    Number of discarded output messages: 0
    Elapsed time since last connection or counters clear: 14:42:40
  Information about (Source, Group)-based SA filtering policy:
    Import policy: 3000
    Export policy: 3002
  Information about SA-Requests:
    Policy to accept SA-Request messages: 2000
    Sending SA-Requests status: enable
  Minimum TTL to forward SA with encapsulated data: 0
  SAs learned from this peer: 0, SA-cache maximum for the peer: 5000
  Input queue size: 0, Output queue size: 0
  Counters for MSDP message:
    Count of RPF check failure: 0
    Incoming/outgoing SA messages: 0/0
    Incoming/outgoing SA requests: 0/0
    Incoming/outgoing SA responses: 0/0
    Incoming/outgoing data packets: 0/0
    Peer authentication: none
    Peer authentication: none
