A network engineer is configuring static routes on a Cisco IOS router to forward traffic to remote IPv6 networks. Which TWO statements accurately describe the requirements and behavior of IPv6 static route configurations? (Select TWO.)
- When specifying an IPv6 link-local address as the next-hop address, the local exit interface MUST also be specified in the command.Cevap
- To configure a floating static IPv6 backup route, the administrative distance value must be set higher than the administrative distance of the primary route.Cevap
- CWhen using a global unicast address as the next hop, specifying the outbound exit interface is mandatory for the route to enter the IPv6 routing table.
- DA default IPv6 static route uses the prefix notation 0.0.0.0/0 followed by the next-hop IPv6 address.
Cevap
The correct statements are: specifying the local exit interface is mandatory when using a link-local next-hop address, and configuring a floating static route requires an administrative distance higher than the primary route.
In Cisco IOS IPv6 static routing, link-local next-hop addresses require the specifying of the local exit interface because link-local addresses are ambient to the specific interface link. Furthermore, creating a backup (floating) static route requires setting an administrative distance value strictly higher than the primary route so it remains inactive until the primary path fails.
