Can there be an ethernet connection between 2 EBGP peers. The ethernet connection will be made using a switch in between the routers. So I just wanted to know will it be technically correct or not?
Also please note that there are 2 scenarios like in one case the EBGP connection is between 1 cisco and 1 juniper router....and in another case the EBGP connection is between 2 cisco routers

The only thing that defines an EBGP peer compaired to a IBGP is the AS number.

So if one router is in AS 100 and the other is in AS 200 (no matter the connection medium) then they share an EBGP peering

To verify the peering run a "sh ip bgp" on your cisco router and check the last setting on each route and it will tell you if it is internal or external.

Also a sh ip bgp <ip address> will show more details about a specific neighbor
router#show ip bgp
BGP table version is 8, local router ID is 192.168.0.231
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure
 
Origin codes: i - IGP, e - EGP, ? - incomplete
