Hi,
If you want to use a pipe after the regular expression, this would be
wrongly interpreted if the regexp was not between quotes. By putting
the regexp in between quotes, the cli knows where the regexp starts en
ends.
I tried it on one of my routers and this does seem to be the case:
router1#sh ip bgp regexp ^$
BGP table version is 39, local router ID is 10.1.10.7
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

router1#sh ip bgp regexp ^$ | i 32768
<nothing>
router1#sh ip bgp quote-regexp "^$" | i 32768
