them, and the TCP connection is closed without any connection setup retry. The configuration information, however, remain unchanged. A TCP connection is required in the following situations: • When a new MSDP peer is created • When you reactivate a previously deactivated MSDP peer connection • When a previously failed MSDP peer attempts to resume operation You can adjust the interval between MSDP peering connection retries. To enhance MSDP security, you can configure an MD5 authentication password for the TCP connection to be established with an MSDP peer. If the MD5 authentication fails, the TCP connection cannot be established. IMPORTANT: The MSDP peers involved in the MD5 authentication must have the same authentication method and password. Otherwise, the authentication fails and the TCP connection cannot be established. To configure MSDP peer connection control: Step 1. Enter system view. 2. Enter MSDP view. Command system-view msdp 3. Deactivate an MSDP peer. shutdown peer-address 4. Configure the interval between MSDP peer connection retries. timer retry interval 5. Configure an MD5 authentication key for the TCP peer peer-address password connection to be established { cipher | simple } password with an MSDP peer. Remarks N/A N/A Optional. Active by default. Optional. 30 seconds by default. Optional. By default, MD5 authentication is not performed before an TCP connection is established. Configuring SA messages related parameters Before you configure SA message delivery, complete the following tasks: • Configure any unicast routing protocol so that all devices in the domain are interoperable at the network layer. • Configure basic MSDP functions. • Determine the ACL rules for filtering SA request messages. • Determine the ACL rules as SA message creation rules. • Determine the ACL rules for filtering SA messages to be received and forwarded. • Determine the TTL threshold for multicast packet encapsulation in SA messages. • Determine the maximum number of (S, G) entries learned from the specified MSDP peer that the router can cache. 164
