At present, China's wireless router industry is developing very rapidly, and its market demand is also very high. Here we mainly introduce Cisco's first dual-band wireless router launched in China, this section describes the features and performance of the vro.

This approach restores the following routers: Cisco 2000 series, 2500 series, 3000 series, Cisco 4000 series using the 680x0 Motorola CPU, and 10.0 series routers running 7000 versions of Cisco IOS systems.

RGMP is designed to be used in combination with the multicast routing selection protocol that supports the distribution tree Join/Prune. The typical protocol is PIM-SM.
The RGMP protocol only specifies the IPv4 multicast route selection operation, excluding IPv6. The Cisco router port Group Management Protocol makes up for the shortcomings of the Internet group management protocol in the snoopIng technical
RGMP: Cisco router port group management protocol (rgmp) makes up for the Internet group management protocol (Igmp: Internet group management protocol) problems in snoopIng technical mechanisms. The rgmp protocol acts between multicast routers and switches. Rgmp allows you to fix multicast data packets forwarded by vswitches in the required vro. Rgmp is designed for backbone swItched networks, which is conn

The user checks network security and requires SSH logon to the core device. Previously, the device used Telnet logon, and the user name and password are transmitted in plaintext, which does not meet the security check requirements.
In fact, the SSH login configuration is very simple, mainly divided into the following steps:
1. Configure the Domain Name

Cisco routers are widely used in network interconnection. Among them, 2500 series routers are widely used in low-end users. So what if you accidentally forget the superuser password of the 2500 series router? Don't be afraid, as long as you can restore as follows:Preparation: a computer running Terminal simulation program can start a Super Terminal in Windows 95/98), and the microcomputer serial port COM1/C
