Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again - SOLVED

Situation : I have installed epel-release-latest-6.noarch.rpm on CentOS release 6.10 (Final) and trying to install 
python-pip, but getting the below error.

[root@puppetlabs tmp]# rpm -ivh epel-release-latest-6.noarch.rpm
warning: epel-release-latest-6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEY

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

Solution:

Edit both /etc/yum.repos.d/epel.repo and /etc/yum.repos.d/epel-testing.repo files, commenting all entries 
starting with mirrorlist=  and uncomment all the entries starting with baseurl= 

epel.repo base url is changed from http://download.fedoraproject.org/pub/epel/6/  to http://del-repos.extreme-ix.org/epel/6/x86_64/repodata/ update the same.
epel-testing.repo base url is changed from http://del-repos.extreme-ix.org/epel/testing/6/ to http://del-repos.extreme-ix.org/epel/testing/6 update the same.

Now run yum repolist command.
