[nsp] using /31s

[matthew zeier]

I'm missing a nugget of clue -

edge2(config)#interface Serial6/0/4:0
edge2(config-if)#ip address 216.23.183.248 255.255.255.254
Bad mask /31 for address 216.23.183.248
edge2(config-if)#ip address 216.23.183.249 255.255.255.254
Bad mask /31 for address 216.23.183.249
edge2(config-if)#ip address 216.23.183.250 255.255.255.254
Bad mask /31 for address 216.23.183.250
edge2(config-if)#ip address 216.23.183.251 255.255.255.254
Bad mask /31 for address 216.23.183.251

216.23.183.0/24 is VSLM'd but has mostly /30s.  I have essentially two /30s
left (216.23.183.248/30, 216.23.183.252/30) and figured I'd double that with
/31s but I'm having issues with IOS accepting it.
