How to configure http/tftp server on cisco router?

Suppose, you want to transfer files between cisco routers. You can choose either tftp or http/https or scp/rcp or ftp. lets say you want to transfer files on disk0: directory on one cisco router to another cisco router. Here are the ways to configure http/tftp server for both IPV6 & IPV4.

Configuring http server on cisco router
==========================

1. R1(config)#ip http server
2. R1(config)#ip http port 8080
3. R1(config)#ip http path disk0:
4. R1(config)#username cisco privilege 15 password 0 cisco

Now, you can transfer files from the above configured router to another router say R2 

using following commands.

1. If you want to copy files using ipv4 address then: 

R2#copy http://[usr]:[passwd]@[ip address]:8080/

Example: 

R2#copy http://cisco:cisco@10.10.10.10:8080/xyz.gz disk0:

*2. If you want to copy files using ipv6 address then: 

R2#copy http://[usr]:[passwd]@[ipv6 address]:8080/[filename] [destination path]

Example:

R2#copy http://cisco:cisco@[2003:db:a::]:8080/xyz.gz disk0:

*Note: ip http server command enables http server for IPV4 as well as IPV6. 

Configuring tftp server on cisco router
==========================
We can simulate tftp server in cisco router, but we have to specify the filename which is being shared among the network. Following command accomplish turning on the tftp server:

R1(config)#tftp-server disk0:

Now, you can transfer files from the above configured router to another router say R2 using following command:

  R2#copy tftp: [destination directory]

Example: copy tftp: disk0:
