Re: [j-nsp] Hardware configuration for cRPD as RR

From a RPD, not cRPD perspective. - 64GB is certainly fine, you might be able to do with 32GB - Unless RRs are physically next to clients, you want to bump default 16kB TCP window to maximum 64kB window, and probably ask account team for window scaling support (unsure if this is true for cRPD, or

[j-nsp] Hardware configuration for cRPD as RR

Hey! cRPD documentation is quite terse about resource requirements: https://www.juniper.net/documentation/us/en/software/crpd/crpd-deployment/topics/concept/crpd-hardware-requirements.html When used as a route reflector with about 20 million routes, what kind of hardware should we use? Docume

Re: [j-nsp] proxy-arp on EVPN irb

As I recall, proxy-arp behavior is proven by looking in the local host arp cache and finding entries for foreign ip’s mapped to the default gateway’s mac address. If that is still occurring, then it would seem that proxy arp functionality is still working and you can move on to tshooting someth

[j-nsp] proxy-arp on EVPN irb

Hi Maybe somebody knows the answer to this one: We migrated some customers to an EVPN domain away from a legacy node that used proxy-arp on its L3 interface. The downstream clients have some funky routing and they are relying on proxy-arp to resolve an offnet address (don't ask me why for our

Hi, we've run in some weird issue with 25G links and FEC between Juniper QFX5120 and Arista. We have functioning links using 25G-SR optics and FEC108 (Reed-Solomon) error correction. On Arista thats default, on the QFX we use set interfaces et-0/0/46 gigether-options fec fec108 This works. Tr
