Concept Guide

The following example shows that sessions are created for static routes for the default VRF.
Dell(conf)#do show bfd neighbors
* - Active session role
Ad Dn - Admin Down
B - BGP
C - CLI
I - ISIS
O - OSPF
O3 - OSPFv3
R - Static Route (RTM)
M - MPLS
V - VRRP
VT - Vxlan Tunnel

Changing IPv6 Static Route Session Parameters
BFD sessions are congured with default intervals and a default role.
The parameters you can congure are: Desired TX Interval, Required Min RX Interval, Detection Multiplier, and system role. These
parameters are congured for all static routes. If you change a parameter, the change aects 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
