BGP Full Router dan Default Route

Next..

Full route adalah metode router distribusi meneruskan prefix yang diterima dari upstream kepada downstreamnya dengan filter out ke downstreamnya permit

Default route adalah metode router distribusi hanya memberikan prefix 0.0.0.0 kepada downstreamnya dengan filter out ke downstreamnya deny biasanya disebut dengan default origin

Contoh Default Route
==> default-originate
==> filter out deny
# sh run
 neighbor 103.23.34.74 remote-as 8888
 neighbor 103.23.34.74 description VENUS
 neighbor 103.23.34.74 weight 1500
 neighbor 103.23.34.74 route-reflector-client
 neighbor 103.23.34.74 default-originate
 neighbor 103.23.34.74 soft-reconfiguration inbound
 neighbor 103.23.34.74 filter-list VENUS-IN in
 neighbor 103.23.34.74 filter-list VENUS-OUT out
# sh ip as-path-access-list VENUS-OUT                                      
AS path access list VENUS-OUT
    deny .*
Contoh Full Route
==>

 neighbor 103.23.34.78 route-reflector-client
 neighbor 103.23.34.78 soft-reconfiguration inbound
 neighbor 103.23.34.78 prefix-list WERKUDORO in
 neighbor 103.23.34.78 filter-list WERKUDORO-IN in
 neighbor 103.23.34.78 filter-list WERKUDORO-OUT out
