Show bgp peers across VSX in CLI

I need to check quite often during maintenance windows how it looks with BGP peers before and after change steps. Especially on VSX is useful to get a quick way how to check something across all virtual systems. Following command list you all BGP peers across virtual systems. It works on non-vsx as well. 

BGP peers output

Command:

echo -e "\e[36m+++++++++++++++++++++++++++\n++    BGP peers status   ++\n+++++++++++++++++++++++++++\n";for i in /proc/vrf/*; do i=${i#*vrf/}; echo -n -e "\e[93m"; vsenv $i | grep  -e "Contex" | sed 's/^Context is set to Virtual Device //' | sed 's/ID/Context/'; echo -n -e "\e[0m"; echo "set virtual-system" $i > /tmp/clishcmd; echo "show bgp peers" >> /tmp/clishcmd; clish -i -f /tmp/clishcmd | grep -vi -e "contex" -e "show" -e "done" -e "flag" -e"^$"; echo; done

Original command idea how to list across contexts is not my own. I got is as advice during TAC case some years ago. You can basically use it to list anything (blue area) in case you are fine with little messy output. It is just simple setup of cmd file for clish:

for i in /proc/vrf/*; do i=${i#*vrf/};  vsenv $i; echo "set virtual-system" $i > /tmp/clishcmd; echo "show bgp peers" >> /tmp/clishcmd; clish -i -f /tmp/clishcmd; done

Hope you'll enjoy it.

Maybe you could use column to show the rows more nicely formatted?

Hi Peter

I want to do the same thing but that script only works for the old kernel VSX, it would need to be updated for the new kernel (specifically the “for i in /proc/vrf/*; do i=${i#*vrf/}” part because they use namespace now instead of vrf.
