I've got a Juniper SRX300 which i'm using to connect to 2 BGP peers. The documentation i've read says this SRX only supports 300,000 BGP routes, so for each peer I created an import policy (based on communities) to only accept my peers customer routes and not the full table. These are roughly 2k routes for peer 1 and 3k routes for peer 2.
It all works fine, however it seems that although only the filtered routes are used the entire table is being stored. For example if I do this I get details of any route from the full table(s)
show route 188.8.131.52 hidden detail
inet.0: 726648 destinations, 726650 routes (3915 active, 0 holddown, 722735 hidden) 184.108.40.206/24 (1 entry, 0 announced) BGP /-101 Next hop type: Router, Next hop index: 1333 Address: 0x1990fe0 Next-hop reference count: 728538 Source: X.X.X.X Next hop: X.X.X.X via ge-0/0/6.0, selected Session Id: 0x0 State: <Hidden Ext> Local AS: XXXXX Peer AS: XXXXX Age: 4:40:08 Validation State: unverified Task: BGP_XXXXX.X.X.X.X AS path: XXXXX 13335 I Aggregator: XXXXX X.X.X.X Communities: XXXXX:XX XXXXX:XXX XXXXX:XXXX XXXXX:XXXX Localpref: 100 Router ID: X.X.X.X Hidden reason: rejected by import policy
So my question was, is the 300k limit only on active routes? Or stored but hidden routes as well?
