Configuration Examples

This section provides the following configuration examples:

• Configuring Traffic Discard: Example

• Configuring a Fixed Default Route: Example

• Configuring a Floating Static Route: Example

• Configuring a Static Route Between PE-CE Routers: Example

Configuring Traffic Discard: Example

Configuring a static route to point at interface null 0 may be used for discarding traffic to a particular

prefix. For example, if it is required to discard all traffic to prefix 2001:0DB8:42:1/64, the following

static route would be defined:

configure

router static

address-family ipv6 unicast

2001:0DB8:42:1::/64 null 0

end

Configuring a Fixed Default Route: Example

A default static route is often used in simple router topologies. In the following example, a route is

configured with an administrative distance of 110.

configure

router static

address-family ipv4 unicast

0.0.0.0/0 2.6.0.1 110

end

Configuring a Floating Static Route: Example

A floating static route is often used to provide a backup path if connectivity fails. In the following

example, a route is configured with an administrative distance of 201.

configure

router static

address-family ipv6 unicast

2001:0DB8::/32 2001:0DB8:3000::1 201

end

Configuring a Static Route Between PE-CE Routers: Example

In the following example, a static route between PE and CE routers is configured, and a VRF is

associated with the static route:

configure

router static

vrf vrf_A

address-family ipv4 unicast

1 2 ... 425 426 427 428 429 430 431 432 433 434 435 ... 445 446
