Configuring Bfd For Rip; Configuring Single-Hop Echo Detection (For A Directly Connected Rip Neighbor); Configuring Single-Hop Echo Detection (For A Specific Destination) - HP 6125XLG Layer 3 - Ip Routing Configuration Manual

Step
2. Enter RIP view.
3. Enable GR for RIP.

Configuring BFD for RIP

RIP detects route failures by periodically sending requests. If it receives no response for a route within a
certain time, RIP considers the route unreachable. This detection mechanism is not fast enough. To speed
up convergence, perform this task to enable BFD for RIP. For more information about BFD, see High
Availability Configuration Guide.
RIP supports the following BFD detection modes:
Single-hop echo detection—Detection mode for a direct neighbor. In this mode, a BFD session is
•
established only when the directly connected neighbor has route information to send.
Single-hop echo detection for a specific destination—In this mode, a BFD session is established to
•
the specified RIP neighbor when RIP is enabled on the local interface.
Bidirectional control detection—Detection mode for an indirect neighbor. In this mode, a BFD
•
session is established only when both ends have routes to send and BFD is enabled on the receiving
interface.
Configuring single-hop echo detection (for a directly connected
RIP neighbor)
Step
1. Enter system view.
2. Configure the source IP
address of BFD echo packets.
3. Enter interface view.
4. Enable BFD for RIP.
Configuring single-hop echo detection (for a specific
destination)
When a unidirectional link occurs between the local device and a specific neighbor, BFD can detect the
failure and the local device does not receive or send any RIP packets through the interface connected to
the neighbor to improve convergence speed. When the link recovers, the interface can send RIP packets
again.
This feature applies to RIP neighbors that are directly connected.
To configure BFD for RIP (single hop echo detection for a specific destination):

Remarks
N/A
By default, RIP GR is disabled.
Remarks

BFD echo packets is not
configured.
