3.动态路由配置:
A.R1:
route ospf 1
 net 202.100.1.0 0.0.0.255 a 0
 net 10.1.1.0 0.0.0.255 a 0

 passive-interface f0/1.10
 passive-interface f0/1.11
B.R2:
route ospf 1
 net 202.100.1.0 0.0.0.255 a 0
 net 202.100.2.0 0.0.0.255 a 0
C.R3:
route ospf 1
 net 202.100.2.0 0.0.0.255 a 0
 net 20.1.1.0 0.0.0.255 a 0
 net 2.2.2.0 0.0.0.255 a 0
 passive-interface f0/1.20
 passive-interface f0/1.22
4.语音网关配置:
A.R1:

①.开启CME服务:
telephony-service
 max-ephones 20
 max-dn 100
 ip source-address 1.1.1.1 port 2000
 no auto-reg-ephone
②.电话号码设置:
ephone-dn 1
 number 1001
ephone-dn 2
 number 1002
③.设置自动注册:
telephony-service
 auto-reg-ephone
 auto assign 1 to 2
此时左边的两个电话直接能够互相拨打。
B.R3:
①.开启CME服务:
telephony-service
 max-ephones 20
 max-dn 100
 ip source-address 2.2.2.1 port 2000
 no auto-reg-ephone
②.电话号码设置:
ephone-dn 1
 number 2001
ephone-dn 2
 number 2002
③.设置手动注册:
ephone 1
 mac-address 0002.17B7.DE38
 type 7960
 button 1:1
ephone 2
 mac-address 00e0.f720.1c46
 type 7960
 button 1:2
此时右边的两个电话直接能够互相拨打。
5.语音网关远程呼叫配置:
A.R1:
dial-peer voice 1 voip
 destination-pattern 20..
 session target ipv4:2.2.2.1
B.R3:
dial-peer voice 1 voip
 destination-pattern 10..
 session target ipv4:1.1.1.1
