Втыкаю 2-ух клиентов в 200-ый VLAN.
Они получают адреса:
router#sh ip dhcp bind
Bindings from all pools not associated with VRF:

Смотрим табличку маршрутизации:
router#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static
route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks
C 172.16.128.0/24 is directly connected, Loopback0
S 172.16.128.2/32 is directly connected, FastEthernet0/1.200
S 172.16.128.3/32 is directly connected, FastEthernet0/1.200
=) Hу не странно ли?
Hа всякий случай пропингуем обоих:
router#ping 172.16.128.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.128.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
router#ping 172.16.128.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.128.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
Вывод, думаю, сделаешь сам.
С уважением,
Pavel.
