EOS: alias to sum up total num of received bgp prefixes

EOS-R1#show ip bgp neighbors 

BGP neighbor is 100.101.1.2, remote AS 100, external link

  Prefix Statistics:

                                   Sent      Rcvd     Best Paths     Best ECMP Paths

    IPv4 Unicast:                688000    818876         808929                   0

    IPv6 Unicast:                     0         0              0                   0

If we like to know the total number of rcvd prefix from all bgp peers, here is the alias command could be useful

alias totbgp show ip bgp neighbors | grep "IPv4 Unicast: \s\s" | awk  '{s+=$4}END{print s}'
