I like putting a switch in front so then I can run two routers behind and g=
et a /29 from the upstream. I can then do router maintenance, upgrades, etc=
. without taking the circuit down.=20

Hello,=20

I have some idea to put switch before bgp router in order to terminate=20
isp 10G uplinks on switch, not router. Main reason is that could be some=20
kind of 1st level of defence against ddos, second reason, less=20
important, save cost of router ports, do many port mirrors.=20

I think about N3K-C3064PQ or Juniper ex4500 because there are quite=20
cheap and a lot of on Ebay.=20

I would like on nexus or juniper try use some feature:=20

- limit udp, icmp, bum packets (bandwith,pps) at ingress tagged port or=20
vlan=20
- create counters: passed and dropped packets, best way to get this=20
counters via snmp oid, sent snmp traps, syslog etc in order to monitor=20
or even as a action shut down port=20
- port mirror from many ports/vlans to multiple port (other anty ddos=20
solutions)=20
- limited bgp but with flowspec to comunicate with another anty ddos=20
devices=20

I'm also wondering how this feature above impact on cpu/whole switch. It=20
can be some performance degradation ot all of this feature are done in=20
hardware, with wirespeeed ? Which model will better to do this ?=20

Thanks for any advice,=20
