[c-nsp] Redistributing ipv6 static default route into eigrpfailure

[Andriy Bilous]

It does work this way - in 12.4(24)T1 anyway. I'm curious what
hardware/software op's using and why is seed metric required there.

R1#sh run int fa0/0
Building configuration...

Current configuration : 129 bytes
!
interface FastEthernet0/0
 no ip address
 duplex auto
 speed auto
 ipv6 address 2620:0:2810:104::252/64
 ipv6 eigrp 14607
end

R1#sh run | i ipv6 route
ipv6 route ::/0 FastEthernet0/0 2620:0:2810:104::1

R1#sh run | s i r e
ipv6 router eigrp 14607
 no shutdown
 redistribute static

R1#sh ipv6 eigrp topology
IPv6-EIGRP Topology Table for AS(14607)/ID(10.0.0.3)

Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
       r - reply Status, s - sia Status

P ::/0, 1 successors, FD is 256
        via Rstatic (256/0)
P 2620:0:2810:104::/64, 1 successors, FD is 28160
        via Connected, FastEthernet0/0
