IPv6 (Cisco) Training - Using the "IPv4 address-family command

Well, this is the first time introduced the family name to the database command Cisco IOS IPv4 "you're in for a real treat, because this article will briefly explain the command, so without further ado let's get started.

The "family IPv4 Address" command is used primarily for multi-topology routing or BGP (MTR) network administrators (like you) command for a session, the standard use of BGP routing prefixes IPv4 addresses, configure the command can.performed both in router configuration mode (Router (config-router) # address-family IPv4) or router configuration mode scope (Router (config-router-scope) # address-family IPv4).

And here is the syntax that is used when the router in router configuration mode:

IPv4 address-family [MDT - Multicast - tunnel - Unicast [VRF] VRF-name - VRF VRF-name]

And here is the syntax that you can use if your router how to configure the router scope:

IPv4 address-family [mdt -Multicast -] unicast

Thus, after inserting the required syntax and beating (pressing) the Enter key, the router is in router configuration Address Family configuration mode "or" how to configure the router address family configuration Scope "in power.

Well, let's say you use the "address-family IPv4 precedence over a router and now you must remove the IPv4 address family configuration (your) to run configuration (running-config file), and end address Familyconfiguration mode, you can both tasks by running the simple word "no" before the command like this:

For example, in router configuration mode:

Router (config-router) # no address-family IPv4

The scope of the router configuration mode:

Router (config-router-scope) # no address-family IPv4

Here are the explanations of the IPv4 address family command keywords are:

MDT - An optional keyword that can be used for IPv4 multicast distribution tree are given(MDT) address family session.

Multicast - An optional keyword that can be used for IPv4 multicast IDs are specified.

Tunnel - An optional keyword that can be used to specify an IPv4 routing session for multipoint tunneling.

Unicast - An optional keyword that can be used to specify the IPv4 unicast address prefixes (by the way, which is standard).

vrfvrf-name - optional keyword that can be used for routing and name of the VPNForwarding (VRF) instance to associate with subsequent IPv4 address family configuration mode commands.

Finally, just in case if you wonder what the message appears when a Cisco router as router mode is in "Address family configuration Router configuration, here's an example:

Router (config-router-af) #

And here's an example of what the prompt looks like router when a Cisco router to "address the family configuration Router configurationMode:

Router (config-router-scope-af) #

I wrote this article for you quickly understand and use the keywords that are associated with the "family IPv4 Address" command, if after reading this article you are thinking that this was not enough information, and you need more, I suggest to my website that you have the techniques to find the latest information about Cisco IPv6 design and implementation.

To your success,
