Configuring Ipv6 Static Routing; Configuring An Ipv6 Static Route; Configuring Bfd For Ipv6 Static Routes - HP FlexFabric 12900E Series Configuration Manual

Configuring IPv6 static routing

Static routes are manually configured and cannot adapt to network topology changes. If a fault or a
topological change occurs in the network, the network administrator must modify the static routes
manually. IPv6 static routing works well in a simple IPv6 network.

Configuring an IPv6 static route

Before you configure an IPv6 static route, complete the following tasks:
•
Configure parameters for the related interfaces.
•
Configure link layer attributes for the related interfaces.
•
Make sure the neighboring nodes can reach each other.
To configure an IPv6 static route:
Step
1. Enter system view.
2. Configure an IPv6 static
route.
3. (Optional.) Set the default
preference for IPv6 static
routes.
4. (Optional.) Delete all IPv6
static routes, including
the default route.

Configuring BFD for IPv6 static routes

BFD provides a general purpose, standard, and medium- and protocol-independent fast failure
detection mechanism. It can uniformly and quickly detect the failures of the bidirectional forwarding
paths between two routers for protocols, such as routing protocols and MPLS. For more information
about BFD, see High Availability Configuration Guide.
IMPORTANT:
Enabling BFD for a flapping route could worsen the situation.

Remarks
N/A
By default, no IPv6
static route is
configured.
The default setting is
60.
The undo ipv6
route-static command
deletes one IPv6 static
route.
