OSPF - What does the 'am' mean in sho ip route x.x.x.x?

[Brian M]

I have two N9Ks connected to each other with OSPF running between them using unnumbered loopbacks. If I go to either switch and do a show ip route x.x.x.x (to it's peer) I get two possible candidate routes. Everything works fine and I can ping my neighbor but I noticed that the second entry has an 'am' after the timestamp. What does this represent?

S1# sho ip route 192.168.0.3
IP Route Table for VRF "default"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]
'%<string>' in via output denotes VRF <string>

192.168.0.3/32, ubest/mbest: 1/0
    *via 192.168.0.3, Eth1/1, [110/41], 00:00:03, ospf-OSPF_UNDERLAY_NET, intra
     via 192.168.0.3, Eth1/1, [250/0], 00:20:10, am

Thanks!!
