来自世界顶级机房的大型路由器,包括AT&T(美国电信)在内的设备都可以动手玩,你还不来?
今天冷博客介绍一个计划和一个网站,都是和骨干路由有关的。
这个计划叫做:俄勒冈大学路由查看计划(University of Oregon Route Views Project)。这是一个好计划,该计划收集了包括多个BGP骨干网路由器的信息,是全世界能连通互联网的地方(中国大陆是个神奇的地方)都能以低权限登录进入进行查看。
该计划地址:http://www.routeviews.org/
这个网站叫做:bgp4.net,网址:http://www.bgp4.net,查看世界路由器页面:http://www.bgp4.net/wiki/doku.php?id=tools:ipv4_route_servers,其中收录了上面说的俄勒冈大学的路由信息。
我们来进行一个测试,对route-server.ip.att.net这个地址使用CRT登陆(使用CMD也可)
可以登录,而且提示普通登录密码:rviews,登陆之后,我们可以查看该路由器的所有信息。
首先我们查看版本信息,如下:
route-server>sh ver
Cisco IOS Software, 7200 Software (C7200-JS-M), Version 12.2(31)SB10, RELEASE SOFTWARE (fc2)

route-server uptime is 1 week, 2 days, 9 hours, 57 minutes
System returned to ROM by reload at 16:31:46 UTC Wed Jan 20 2010
System restarted at 16:33:43 UTC Wed Jan 20 2010
System image file is “disk2:c7200-js-mz.122-31.SB10.bin”
Last reload reason: Reload commandCisco 7206VXR (NPE-G1) processor (revision A) with 983040K/65536K bytes of memory.
Processor board ID 29814540
SB-1 CPU at 700Mhz, Implementation 0×401, Rev 0.2, 512KB L2 Cache

PCI bus mb1 (Slots 1, 3 and 5) has a capacity of 600 bandwidth points.
Current configuration on bus mb1 has a total of 0 bandwidth points.
This configuration is within the PCI bus capacity and is supported.PCI bus mb2 (Slots 2, 4 and 6) has a capacity of 600 bandwidth points.
Current configuration on bus mb2 has a total of 0 bandwidth points.
This configuration is within the PCI bus capacity and is supported.Please refer to the following document “Cisco 7200 Series Port Adaptor
Hardware Configuration Guidelines” on Cisco.com <http://www.cisco.com>
for c7200 bandwidth points oversubscription and usage guidelines.3 Gigabit Ethernet interfaces
509K bytes of NVRAM.47040K bytes of ATA PCMCIA card at slot 0 (Sector size 512 bytes).
62592K bytes of ATA PCMCIA card at slot 2 (Sector size 512 bytes).
16384K bytes of Flash internal SIMM (Sector size 256K).
Configuration register is 0×2102
从中我们可以看到这是一部Cisco 7206VXR 配备了高端NPE-G1引擎,而且学习了大量的BGP路由信息,如下:
oute-server>sh ip route summary
IP routing table name is Default-IP-Routing-Table(0)
IP routing table maximum-paths is 32
Route Source Networks Subnets Overhead Memory (bytes)
connected 0 1 64 152

internal 3199 3749228
Total 138353 169177 19477184 50080980
而这个路由器只开了1个G口,而且流量不大,因此冷博客觉得这个路由器只是做演示或者备份的。
你也赶紧动手来玩吧!
