**How to post configuration snippets** [![]() ](https://vimeo.com/284215336) The discourse forum software supports code snippets. To keep everything nice and readable, please “code” your configuration snippets. **How not to add configuration snippets** Don’t do this: hostname PE1 interface Loopback0 ip address 2.2.2.2 255.255.255.255 ! interface GigabitEthernet0/0 ip address 10.255.2.113 255.255.0.0 shutdown duplex auto speed auto media-type rj45 It’s difficult to see the difference between regular text and configuration snippets. It’s messy! **Use the code button** Select your configuration snippet and use the code button. See screen shot below: ![](https://cdn-forum.networklessons.com/uploads/default/original/1X/512eed0bb5b2620ad0d0b3be6bdce19bebf66556.JPG) You will know when it works, as the text you selected will become indented. Over in the preview pane, you will see the text coded with a colored background. Your configuration snippet now looks like this: ``` hostname PE1 interface Loopback0 ip address 2.2.2.2 255.255.255.255 ! interface GigabitEthernet0/0 ip address 10.255.2.113 255.255.0.0 shutdown duplex auto speed auto media-type rj45 ``` Much, much cleaner! - Instead of the code button, you can also use HTML: - `
my configuration snippet
` for configuration snippets. - or `hostname R1` for commands. **Add only the relevant configuration snippet** Don’t post the entire configuration. For example, if you only have a question about MP-BGP on your router then don’t paste the entire configuration: ``` Building configuration... Current configuration : 3769 bytes ! !

Only paste the relevant configuration snippet that we need to answer your question: ``` router bgp 234 bgp log-neighbor-changes neighbor 4.4.4.4 remote-as 234 neighbor 4.4.4.4 update-source Loopback0 ! address-family ipv4 no neighbor 4.4.4.4 activate exit-address-family ! address-family vpnv4 neighbor 4.4.4.4 activate neighbor 4.4.4.4 send-community extended exit-address-family ! address-family ipv4 vrf CUSTOMER redistribute ospf 2 exit-address-family ``` Nice, clean, and easy on the eyes. **Don’t add sensitive information** Our forum is read-only to the public so remove any sensitive information like IP addresses or usernames in your configuration snippets! ---
