ISR4000 内建了完整的 WAAS 功能,称为 ISR-WAAS。其功能与WAVE版、vWAAS版、SRE版都完全相同,包含完整的TCP优化、重复数据删除、和压缩功能。除此之外,ISR4000 与 ASR1000 一样,内建了 AppNav 功能,用来取代传统的 WCCP,以提升整体性能。

在 ISR4000 上使用 ISR-WAAS 的硬件要求:

  1. 至少 8G 内存 (default 4G),1300 connection以上需升级至 16G 内存
  2. 至少 200G 硬盘空间。4300 与 4400 都支持 NIM-SSD 硬盘接口卡。此外,4300 的主板上还有一个 mSATA 端口,可以安装一个mSATA 硬盘,但不能与 NIM-SSD 同时使用。

ISR-WAAS 的安装非常简单,在 CLI 敲入 service waas enable 即有可自动配置 ISR-WAAS 与 AppNav。

ISR-WAAS 与 AppNav 的运作方式

ISR-WAAS 的自动配置

先配置一个 loopback 端口,用来连接到 ISR-WAAS 服务。

interface Loopback0
 ip address

确认一下,从此网段可以 ping 得到 WAAS Central Manager。(如果使用了 DMVPN+EIGRP 的话,记得把这个网段加到 EIGRP 的 network 里,或是在总部端,加上一笔静态路由)

ISR4321#ping source
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to, timeout is 2 seconds:
Packet sent with a source address of
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms

再于 # 模式下,启用 ISR-WAAS 自动配置 (不是 conf t 模式下),回答 WAAS 服务的 IP(与 loopback 同网段的一个地址),Central Manager 地址,与路由器连接广域网的端口(如使用VPN时,应选择 Tunnel 端口)。

ISR4321# service waas enable

An internal IP interface and subnet is required to deploy a WAAS service on this router.
This internal subnet must contain two usable IP addresses that can route and communicate with the WAAS Central Manager (WCM).

The following ip address type supported for ISR-WAAS
1) ipv4
2) ipv6

Select ip address type (1 or 2): 1

Enter the IPV4 address to be configured on the WAAS service:

The following ip address type supported for Host on Router
1) ipv4
2) ipv6

Select ip address type (1 or 2): 1
The following ip address type for WCM
1) ipv4
2) ipv6

Select ip address type (1 or 2): 1

Enter the IP address of the WAAS Central Manager (WCM):

The following IP interfaces are currently available on the router:

Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0/0 YES NVRAM up up
GigabitEthernet0/0/1 YES NVRAM up up
GigabitEthernet0 unassigned YES NVRAM administratively down down
Loopback0 YES NVRAM up up

Enter a WAN interface to enable WAAS interception (blank to skip) []: gi0/0/1

Enter additional WAN interface (blank to finish) []:

** Configuration Summary: **

a) WAAS Image and Profile Size:

c) WAAS Central Manager:

d) Router WAN Interfaces:

Choose one of the letter from 'a-d' to edit, 'v' to view config script, 's' to apply config [s]: s

The configuration will be applied and the status of the WAAS service will be displayed after deployment

Installing harddisk:/ISR-WAAS-5.4.1a.17.ova


小提示:如果 WAAS 服务的 IP使用 LAN 端口网段 ,需注意 LAN 端口要是 UP 的状态,否则可能会装不起来。

小提示:如果一个站点有两台路由器,得把 AppNav 配置手动修改成 cluster 模式。参考:链接
