5. 配置二层端口
5.1. 配置Trunk:
Router(config)# interface fastethernet x/y （以fastethernet为例，gigabitethernet一样）
Router(config-if)# shutdown
Router(config-if)# switchport
Router(config-if)# switchport mode dynamic desirable
Router(config-if)# switchport trunk encapsulation dot1q
Router(config-if)# no shutdown
Router(config-if)# end
Router# exit
如果要配置二台6509之间的Trunk联接，首先将二6509用千兆光纤相联好，然后分别配置二相联端口的trunk，可以是只用一双光纤，或用二对光纤做port channel，配置如下：
一双光纤相联时，分别在二台65上进行以下的配置：
interface GigabitEthernet1/1
no ip address
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 1
二对光纤做port channel，分别在二台65上进行以下的配置：：
interface port-channe1
no ip address
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 1
!
interface GigabitEthernet1/1
no ip address
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 1
channel-group 1 mode on
!
interface GigabitEthernet1/2
no ip address
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 1
channel-group 1 mode on
6. 配置HSRP
在其中一台65上按下面模版进行配置
interface Vlan x
ip address x.x.x.x x.x.x.x
no ip redirects
no ip directed-broadcast
standby 1 priority 100 preempt
standby 1 ip y.y.y.y
!
