Each customer consisting of the endpoint addresses &#8211; 172.16.1.1 and 172.16.2.1. We will place each customer within its own VRF. Traffic will be initiated from one end of the customers site (i.e the Customer Edge). Up to the Provider Edge via the necessary VRF. From this point it will then be label switched across the MPLS core, then routed back down to the other Customer Edge. Sounds confusing? Don&#8217;t worry, we will break each part down piece by piece.<\/p>\n<p>Within this tutorial our topology will be built upon on 5 key steps.

First of all we will enable the <strong>Label Distribution Protocol<\/strong> <strong>(LDP)<\/strong> across our Provider and Provider-Edge routers.<br \/>\nThis is done by enabling LDP at a global level, then enabling it on a per interface level on each interface within the MPLS domain, i.e Provider Edge to Provider and Provider to Provider. Please refer to Figure 1 for reference.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"PPE_Configuration\"><\/span>P\/PE Configuration<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Below shows the commands you would configure on each router within the MPLS domain.<\/p>\n<pre class=\"prettyprint\">mpls ip   interface giX\/X     mpls ip<\/pre>\n<h3 id=\"verification\"><span class=\"ez-toc-section\" id=\"Verification\"><\/span>Verification<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>There are 2 commands useful for verifying your configuration.<\/p>\n<p>First of all use <span class=\"codeinline\">show mpls interfaces<\/span> to show which interfaces LDP is enabled on.

This will ensure each PE knows the next hop (i.e the PE peers loopback address) required to get to the customers network. Traffic will then be sent over the MPLS core due to each PE having an LSP (Label Switched Path) to its peers loopback address.<\/p>\n<p>Great! However, there is another point to address (excuse the pun) which is <strong>route separation<\/strong>. As you have seen within our topology we have 2 customers, both with the same address ranges.<br \/>\nIn order to distinguish these routes, <strong>route distinguishers (RD)<\/strong> are used. This is a unique number prepended to each route within a VRF to identify it as belonging to that particular VRF or customer<sup>[1]<\/sup>.<\/p>\n<p><strong>Why use MP-BGP and not legacy BGP?<\/strong><br \/>\nMP-BGP supports 2 key features over legacy BGP &#8211; VPNv4 and Extended Communities.<\/p>\n<ul>\n<li><strong>VPNv4 Capability &#8211; <\/strong>This simply means that routes containing a route distinguisher can be exchanged.<\/li>\n<li><strong>Extended Communities<\/strong> &#8211; In short, these use route targets, applied to the VRF , to control the import and export of routes across the VRFs.<\/li>\n<\/ul>\n<p>With all that said, lets move onto the configuration.<br \/>\n<span class=\"uk-badge\">NOTE<\/span> In the configuration below each neighbor address is the loopback of its peer.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"PE-1_Configuration\"><\/span><strong>PE-1 Configuration<br \/>\n<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<pre class=\"prettyprint\">router bgp 65536  \r\n bgp log-neighbor-changes\r\n neighbor 192.168.0.6 remote-as 65536\r\n neighbor 192.168.0.6 update-source Loopback0\r\n !\r\n address-family vpnv4\r\n  neighbor 192.168.0.6 activate\r\n  neighbor 192.168.0.6 send-community extended\r\n exit-address-family<\/pre>\n<h3><span class=\"ez-toc-section\" id=\"PE-2_Configuration\"><\/span><strong>PE-2 Configuration<br \/>\n<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<pre class=\"prettyprint\">router bgp 65536  \r\n bgp log-neighbor-changes\r\n neighbor 192.168.0.3 remote-as 65536\r\n neighbor 192.168.0.3 update-source Loopback0\r\n !\r\n address-family vpnv4\r\n  neighbor 192.168.0.3 activate\r\n  neighbor 192.168.0.3 send-community extended\r\n exit-address-family<\/pre>\n<h3 id=\"verification\"><span class=\"ez-toc-section\" id=\"Verification-2\"><\/span>Verification<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>To verify our configuration we will first check the adjacency via <span class=\"codeinline\">show ip bgp summary<\/span>.
