Concept Guide
To disable all VRRP sessions on an interface, sessions for a particular VRRP group, or for a particular VRRP session on an interface, use the
following commands.
• Disable all VRRP sessions on an interface.
INTERFACE mode
no vrrp bfd all-neighbors
• Disable all VRRP sessions in a VRRP group.
VRRP mode
bfd disable
• Disable a particular VRRP session on an interface.
INTERFACE mode
no vrrp bfd neighbor ip-address
Congure BFD for VLANs
BFD on Dell Networking systems is a Layer 3 protocol.
Use BFD with routed virtual local area networks (VLANs). BFD on VLANs is analogous to BFD on physical ports. If you enable the no
routing protocol, and a remote system fails, the local system does not remove the connected route until the rst failed attempt to send a
packet. If you enable BFD, the local system removes the route when it stops receiving periodic control packets from the remote system.
There is one BFD agent for VLANs and port-channels that resides on RP2, as opposed to the other agents that are on the line card.
Therefore, the 100 total possible sessions that this agent can maintain is shared for VLANs and port-channels.
Conguring BFD for VLANs is a two-step process:
1 Enable the BFD globally. Refer to Enabling BFD Globally.
2 Establish sessions with VLAN neighbors. Refer to Establish Sessions with VLAN Neighbors.
