I've found an interesting issue and I wanted to get some thoughts before talking to JTAC about it.
I have a few of MX480s. In the past, I've advertised a dedicated /24 from my lab to my providers upstream. That /24 was never learned by my primary MX. The issue comes down to either the MX or the Cisco filtering routes that are from the same ASN. It's been a couple of years since I ran across this and I can't remember who was at fault. This behavior is biting my with regard to my DR site. At my DR, I have a SRX with say ASN 1234. It's advertising a /24. At my primary site, I also use ASN1234. I do not receive the /24 via BGP. So, either the Cisco (7600 I think) isn't advertising the route to me because it's from my ASN - OR - The MX is filtering it because it's from my ASN and coming in on a eBGP link. If it's the MX, I'm certain I can write an import filter, but I'm having an issue hunting down syntax on that. If it's the Cisco, then I can yell at the provider to have them open a TAC case. Like I said, I ran across this a few years ago, but can't remember who was at fault. I could build a multi-hop neighbor relationship to get around this, but surely there's a simpler solution... _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
