Changing IPv6 Static Route Session Parameters
BFD sessions are configured with default intervals and a default role.
The parameters you can configure are: Desired TX Interval, Required Min RX Interval, Detection Multiplier, and system role. These
parameters are configured for all static routes. If you change a parameter, the change affects all sessions for static routes.
To change parameters for static route sessions, use the following command .
• Change parameters for all static route sessions.
CONFIGURATION mode
ipv6 route bfd [vrf vrf-name][prefix-list prefix-list-name] interval milliseconds min_rx
milliseconds multiplier value role [active | passive]
To view session parameters, use the show bfd neighbors detail command, as shown in the examples in Displaying BFD for BGP
Information
Configure BFD for OSPF
When you use BFD with OSPF, the OSPF protocol registers with the BFD manager. BFD sessions are established with all neighboring
interfaces participating in OSPF. If a neighboring interface fails, the BFD agent notifies the BFD manager, which in turn notifies the OSPF
protocol that a link state change has occurred.
Configuring BFD for OSPF is a two-step process:
1. Enable BFD globally.
2. Establish sessions with OSPF neighbors.
