GATEWAY TYPE PREFIX TABLE
=========================
Prefix: 1#* (Default gateway-technology)
Zone a master gateway list:
192.168.100.1:1720 r1
试验结果: 2001----calling ----> 1001 是可通的,如下图，原因是有default gateway-technology的缘故
但1001----calling--->2001 不通
不过，静态写明细e164条目和缺省路由都不是常规的部署方案，因为GK可能存在多个default gateway
通常的办法是添加tech-prefix ,通常我们说的区号
PS： translation rules
R1(config)#gatekee
R1(config-gk)#no gw-type-pre 1# default \\取消掉default gateway

R1(config-dial-peer)#tech-prefix 2#
R2(config)#dial-p voice 1000 voip \\呼叫1...的号码前,加上1#
R2(config-dial-peer)#tech-prefix 1#
但是还是有个问题,当2#+号码送到R2上是没办法处理的 ,R1 同理
所以R1和R2要做入向裁号
R2(config)#voice translation-rule 1
R2(cfg-translation-rule)#rule 1 /^.*\(2...\)$/ /\1/
R2(cfg-translation-rule)#exit
R2(config)#voice translation-profile for2# \\定义profile name

也可以在dial-peer voice 1111 voip 下调用,看实际情况的应用.

3- GK Zone-Prefix
一般来说，zone prefix是GK的管理域，一个GK可以有多个zone, zone是用来管理带宽的 ,它必须跟tech-prefix一起使用
3.1 单GK 单 zone
这种情况用的很少
R2(config-if)#int f0/1
R2(config-if)#no h323-gateway voip tech-prefix 2#
R2(config-if)#h323-gateway voip tech-pre 1#
R2(config-if)#gateway
R2(config-gateway)#exit
R1(config)#dial-pee voice 2000 voip
R1(config-dial-peer)#no tech-prefix 2#
R1(config-dial-peer)#tech-prefix 1#
R1(config-dial-peer)#end
\\这样R1和R2都对1#有管理权
R1(config)#gatekeeper
R1(config-gk)#zone prefix a 1 gw-priority 10 r1
R1(config-gk)#zone prefix a 1 gw-priority 0 r2
R1(config-gk)#zone prefix a 2 gw-pri 10 r2
R1(config-gk)#zone prefix a 2 gw-pri 0 r1
R1#show gatekeeper gw-type-prefix
GATEWAY TYPE PREFIX TABLE
=========================
Prefix: 1#*
Zone a master gateway list:
192.168.100.1:1720 r1
192.168.3.1:1720 r2
Zone a prefix 2* priority gateway list(s):
Priority 10:
192.168.3.1:1720 r2
Zone a prefix 1* priority gateway list(s):
Priority 10:
192.168.100.1:1720 r1
\\由于r1和r2都宣称管理tech-prefix是1#的号码,所以向GK查询号码时候"1#1001"
"1#1002"如何路由时,GK认为r1r2均是1#号码的管理者,当2001----calling----1001时 剥离1#前最后,1001号码属于1*归属r1管理.
Gk告诉r2应该向r1发起链接

R1/2(config-if)#no h323-gateway voip interface
确保没有任何endpoints有注册,如下:
R1#sh gatek endpoints

R2(config-if)# h323-gateway voip tech-prefix 2# \\宣告对2#管理
R1(config)#dial-peer voice 2000 voip \\打2#的标
R1(config-dial-peer)#no tech-prefix 1#

Gk的决策树：
分为
1管辖层面，不能决定路由，但可以提前拒绝
2 路由层面，e164号码，tech-prefix+zone prefix,default gw technology + zone prefix每个条件可以决定路由
R2向gk 查询号码1#1001,1#1002,gk摘除1#之后1开头的号码都属于1* 归属zone a 1管辖，在zone a 1里1#归属于r1管理，所以gk告诉r2向r1 发起呼叫连接
4- 多 GK多zone
这里我们只谈GK peer to peer
1-在r1和r2分别作zone local和指定zone remote
R1#sh run | be gateke
gatekeeper
zone local a cisco.com 1.1.1.1
zone remote b cisco.com 2.2.2.2 1719
gw-type-prefix 2#* hopoff b
no shutdown
R2#sh run | be gateke
gatekeeper
zone local b cisco.com 2.2.2.2
zone remote a ciscocom 1.1.1.1 1719
gw-type-prefix 1#* hopoff a
no shutdown
2-在r1 和r2分别注册到gk
R2#sh run int f0/1
