The bgp_multiview_topo1 test had two issues a) An abbundance of sleeps that are not necessary b) The convergence time was too short. The upshoot of this is that the test goes from 72 -> 33 seconds run time on my machine. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com> |

Tests executed
Check if FRR is running
Test is executed by running
vtysh -c "show logging" | grep "Logging configuration for"
on router R1. This should return the logging information for all daemons registered
to Zebra and the list of running daemons is compared to the daemons started for this
test (zebra and bgpd)
Verify for BGP to converge
BGP is expected to converge on each view within 60s total time. Convergence is verified by executing
vtysh -c "show ip bgp view 1 summary"
vtysh -c "show ip bgp view 2 summary"
vtysh -c "show ip bgp view 3 summary"
and expecting 11 routes seen in the last column for each peer. (Each peer sends 11 routes)
Verifying BGP Routing Tables
Routing table is verified by running
vtysh -c "show ip bgp view 1"
vtysh -c "show ip bgp view 2"
vtysh -c "show ip bgp view 3"
and comparing the result against the stored table in the r1/show_ip_bgp_view_NN.ref files (with NN 1, 2, 3) (A few header and trailer lines are cut/adjusted ahead of the compare to adjust for different output based on recent changes)
