Traspasing Juniper Bgp To Cisco
Hey,
Testing some stuff in a GNS3-based lab, I put this config into a router (7200 series, running IOS 15.3):
ip route 0.0.0.0 0.0.0.0 Null0
!
router bgp 65002

When I do a 'Show ip bgp' , I don't see the route 0.0.0.0/0 being installed in the BGP table. I do see it as a static route in the IP routing table though, as expected.
I created another static route (different than 0.0.0.0/0) also pointing to Null0 and it did indeed showed up in the BGP table.
If I add the 'default-information originate' command in router config mode, the 0.0.0.0/0 does appear in the BGP table, which is also an expected result, IMHO. The same happens if instead of using 'default-information originate', I enter 'network 0.0.0.0'. Again, this is expected.
Question: the 'redistribute static' command works for all static routes but for 0.0.0.0/0 ? I couldn't find any documentation indicating so, but my lab results tell me otherwise.
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 1.1.1.1 hidden detail
I placed a call to Sony tech support and was given the following instructions and was able to resolve the issue:1. Download following drivers and install them in the order in which they are listed:- Original Sony Shared Library (once installed reboot the system)- Original Sony Notebook Utilities (once installed reboot the system)- VAIO Content Components (no reboot require after this driver)- Setting Utilities Series Update (once installed reboot the system)- VAIO event service update (once installed reboot the system)3. I am not sure if the same drivers that apply to my laptop are available for all models, but you can check.2. Go to the sony vaio drivers website and select the model of laptop and OS you require.

inet.0: 726648 destinations, 726650 routes (3915 active, 0 holddown, 722735 hidden)
So my question was, is the 300k limit only on active routes? Or stored but hidden routes as well?
Thanks
