Hi All,
Имеется c3600 c 12.2.12l
Имееются два интерфейса
interface Serial1/0
description P268-2048
bandwidth 2048
ip address 192.168.200.254 255.255.255.252
ip accounting output-packets
ip nbar protocol-discovery
ip route-cache policy
ip route-cache flow
no ip mroute-cache
ip policy route-map to-vpn
service-policy output VOICE
serial restart-delay 0
ip rtp header-compression
и
interface Serial3/1
description Nsk-backup
bandwidth 2048
ip address 192.168.200.213 255.255.255.252
ip nbar protocol-discovery
ip route-cache policy
ip route-cache flow
ip ospf message-digest-key 10 md5 7 153A1E153E242A213C
ip ospf cost 96
no ip mroute-cache
ip policy route-map to-vpn
service-policy output VOICE
serial restart-delay 0
ip rtp header-compression
Имеется ospf
router ospf 1
log-adjacency-changes
area 0 authentication message-digest
redistribute connected
redistribute static
redistribute rip
passive-interface FastEthernet0/0.2
network 192.168.119.0 0.0.0.255 area 0
network 192.168.200.0 0.0.0.255 area 0
default-information originate
И в результате имеем маршрут через 2 интерфейса:
sh ip ro 10.1.1.1
Routing entry for 10.1.1.0/24
Known via "ospf 1", distance 110, metric 97, type inter area
Redistributing via rip

Routing Descriptor Blocks:
* 192.168.200.214, from 192.168.200.246, 00:52:05 ago, via Serial3/1
Route metric is 97, traffic share count is 1
192.168.200.253, from 192.168.200.246, 00:52:05 ago, via Serial1/0
Route metric is 97, traffic share count is 1
Однако, звездочка _всегда_ установлена в первый маршрут.
Hетфлоу показывает, что и действительно, трафик идет через один интерфейс.
Хотя, с другой стороны, на такой же 3660, правда с древним 12.2.8T, все
выглядит правильно:
npu1-cr3660-1#sh ip ro 192.168.22.220
Routing entry for 192.168.22.0/24
Known via "ospf 1", distance 110, metric 20, type extern 2, forward metric
96

Может есть идеи?
Спасибо!
