Title:
  routing table does not show dynamic routes

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Dynamic routes gotten from ICMP-redirect message are not shown in the
  routing table.

  Here is an example from my network:
  My default router is 147.91.174.17 which had sent back ICMP-redirect packet to change route to 147.91.174.5

  $route
  Kernel IP routing table
  Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
  default         147.91.174.17   0.0.0.0         UG    0      0        0 eth0
  147.91.174.0    *               255.255.255.0   U     1      0        0 eth0
  $netstat -rt
  Kernel IP routing table
  Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
  default         147.91.174.17   0.0.0.0         UG        0 0          0 eth0
  147.91.174.0    *               255.255.255.0   U         0 0          0 eth0
  $ ip route show
  default via 147.91.174.17 dev eth0  proto static 
  147.91.174.0/24 dev eth0  proto kernel  scope link  src 147.91.174.16  metric 1 

  But packets to certain hosts are routed to a different router:
  # ip route get 82.94.219.115
  82.94.219.115 via 147.91.174.5 dev eth0  src 147.91.174.16 
      cache <redirected>

  As you can see,  route to 147.91.174.5 is not listed in the main
  routing table.

  Is this a bug or expected behaviour?
