A network administrator needs to configure a secondary floating default route on router Edge-2 toward an upstream ISP. The primary default route is learned dynamically via OSPFv3 with a administrative distance of 110. The backup route must forward all unmatched traffic out local interface GigabitEthernet0/1 to the ISP router's link-local next-hop address fe80::250:56ff:fea1:2b3c using an administrative distance of 130. Complete the global configuration command required on router Edge-2 to create this fully specified floating default static route.
Cevap:ipv6 route 【::/0】 GigabitEthernet0/1 fe80::250:56ff:fea1:2b3c 【130】
Cevap
The first blank requires '::/0' to designate the default IPv6 prefix, and the second blank requires '130' to set the administrative distance for the floating static route.
An IPv6 default static route uses the prefix '::/0'. When using a link-local address (fe80::/10) as a next-hop, Cisco IOS requires specifying the local exit interface alongside the link-local address because link-local addresses are scope-bound to a specific link. To make the static route a floating backup path behind OSPFv3 (AD 110), an administrative distance parameter of 130 is added to the end of the global configuration command syntax: 'ipv6 route <prefix/length> <exit-interface> <next-hop-address> [administrative-distance]'.
