Switching

Hi ,

İ am a new person to Junipeer switching  from Cisco. One Costumer , he has two different ISP via Fiber Optic Line. So will configurate two vlan on switch and bgp configuration on EX4500 switch. Is it possible to make  bgp on EX4500 switch ? Is there any default configuration about vlan and bgp.

Thanks so much. 

Hi Ilyas

You dont need to do vlans on a juniper to do routing. So we just need to assign a /30 to each fiber link and turn on BGP and it will route. You need 1 AFL per EX4500 or 2 for any size of a vitual chassis. See this section for the routing table size, this type of device will not scale very large because it wasn't meant to serve as a border router.

As you can see there are only 10k routes supported, the current internet size is well over 300k per neighbor being peered with.

switch1> configure

switch1# set interface ge-0/0/0.0 family inet address 1.1.1.1/30

switch1# set interface ge-0/0/1.0 family inet address 1.1.1.5/30

Turn on BGP as follows

set protocols bgp group eBGP type external
set protocols bgp group eBGP log-updown
set protocols bgp group eBGP damping
set protocols bgp group eBGP local-as 64741
set protocols bgp group eBGP graceful-restart
set protocols bgp group eBGP neighbor 1.1.1.2 local-address 1.1.1.1
set protocols bgp group eBGP neighbor 1.1.1.2 peer-as 65100
set protocols bgp group eBGP neighbor 1.1.1.6 local-address 1.1.1.5
set protocols bgp group eBGP neighbor 1.1.1.6 peer-as 65101

Thanks so much,

 can you send me a default configuration of vlan. one port will be trunk and allowed only one vlan, one of the lan ports will be access port .

If you send the configuration, i will be very glad you.

thanks
