+R2 is DUT and peers with R1 and R3 in default bgp instance.
+
+Following tests are covered under BGP conditional advertisement functionality.
+Conditional advertisement
+-------------------------
+TC11: R3 BGP convergence, without advertise-map configuration.
+      All routes are advertised to R3.
+TC21: exist-map routes present in R2's BGP table.
+      advertise-map routes present in R2's BGP table are advertised to R3.
+TC22: exist-map routes not present in R2's BGP table
+      advertise-map routes present in R2's BGP table are withdrawn from R3.
+TC31: non-exist-map routes not present in R2's BGP table
+      advertise-map routes present in R2's BGP table are advertised to R3.
+TC32: non-exist-map routes present in R2's BGP table
+      advertise-map routes present in R2's BGP table are withdrawn from R3.
+TC41: non-exist-map route-map configuration removed in R2.
+      advertise-map routes present in R2's BGP table are advertised to R3.
+TC42: exist-map route-map configuration removed in R2
+      advertise-map routes present in R2's BGP table are withdrawn from R3.
+
+Conditional advertisement along with Route-map Filter
+-----------------------------------------------------
+TC51: exist-map routes present in R2's BGP table, with route-map filter.
+      All routes are withdrawn from R3 except advertise-map routes.
+TC52: exist-map routes present in R2's BGP table, without route-map filter.
+      All routes are advertised to R3 including advertise-map routes.
+TC53: non-exist-map routes present in R2's BGP table, with route-map filter.
+      All routes are withdrawn from R3 including advertise-map routes.
+TC54: non-exist-map routes present in R2's BGP table, without route-map filter.
+      All routes are advertised to R3 except advertise-map routes.
+TC61: exist-map routes not present in R2's BGP table, with route-map filter.
+      All routes are withdrawn from R3 including advertise-map routes.
+TC62: exist-map routes not present in R2's BGP table, without route-map filter.
+      All routes are advertised to R3 except advertise-map routes.
+TC63: non-exist-map routes not present in R2's BGP table, with route-map filter.
+      All routes are withdrawn from R3 except advertise-map routes.
+TC64: non-exist-map routes not present in R2's BGP table, without route-map filter.
