Interesting, but much routes have dead gw (193.106.112.91). It does anonce nothing. But routes are still in sh ip route table
asr# sh ip route | i 193.106.112.91
B 31.207.128.0/18 [180/0] via 193.106.112.91, 2w2d

Seems like asr think that route have a greater netmask, and does not delete route from "ip route" table, even if neighbor doesn't announce network anymore. I plan to downgrade ios. Because this behavior, in my opinion, is not normal.
