Fryguy — Mon, 13 Jan 2014 13:00:22 +0000

Ok, you have survived all my individual posts and now, finally, the whole workbook in PDF format. You can find it…. CLICK HERE If you are looking for more information, I have recently published a 500+ page JNCIE Enterprise prep guide via LeanPub. You can find more information about that workbook at this link – http://www.fryguy.net/2014/10/31/jncie-ent-prep-guide-has-been-published/. [][1]

Junos – Route Filtering

Fryguy — Fri, 10 Jan 2014 13:05:57 +0000

And now the final post before the whole workbook is posted, Route Filtering

Ok, lets discuss Route Filtering in this lab, and to keep is simple, we will use eBGP for the routing protocol. For this lab we will need to create another loopback on R4 for 44.44.44.44/32.

The goal of this lab is in 3 parts.

Junos – System Services

Fryguy — Wed, 08 Jan 2014 13:05:42 +0000

Now to talk about some of the system services. Services like NTP, Telnet, SSH, SNMP, Monitor and LAG interfaces. This is a biggie!

There are a few services that I wanted to cover but wanted to wait until near the end. The reason for waiting is that I wanted you to focus on the configuration on the protocols and not so much the access and supporting features. Plus, having a routing protocol configured simplifies the testing of these commands.

Junos – NHRP

Fryguy — Mon, 06 Jan 2014 13:05:04 +0000

Ok, now we can reset back to some basic stuff – NHRP or VRRP!

Before beginning, reset all configs back to rescue/base.

Junos only supports the standard NHRP, VRRP. For this lab we will configure a VRRP address of 192.168.23.23 on the link between J2 and J3. We will then PING that address from R4 to validate traffic. In order to test failover, we will deactivate an interface on J2 (Master VRRP) and check that J3 is now the active VRRP device.

Junos – eBGP Juniper to Cisco (and some MD5)

Fryguy — Fri, 03 Jan 2014 13:05:34 +0000

Ok, time for some eBGP between Cisco and Juniper

Before we begin this lab, reset all the configs back to the rescue/base before beginning.

Ok, let’s configure our J1-J2-J3 OSPF Configuration.

J1:

Junos – eBGP Juniper to Juniper

Fryguy — Wed, 01 Jan 2014 13:05:05 +0000

Time for some eBGP between Juniper devices

Ok, time for some eBGP configurations. Of course, first thing we need to do – reset to the rescue/base configs. You can do that now.

We will create an iBGP session between J1 and R4 using ASN 14 and we will also create an iBGP session between J2 and J3 using ASN 23.

Junos – iBGP with Juniper and Cisco

Fryguy — Mon, 30 Dec 2013 13:05:08 +0000

Now time for some iBGP with Cisco and Juniper

Ok, again we need to reset the lab to the rescue config on J1, J2 and J3, and load the base on R4.

Now that you have done that, we can configure OSPF area 0 on J1, J2, and J3. We will advertise the loopbacks into OSPF as well.

J1:

jfry@J1> edit

Entering configuration mode

[edit]

jfry@J1# edit protocols ospf area 0

[edit protocols ospf area 0.0.0.0]

jfry@J1# set interface ge-0/0/0

[edit protocols ospf area 0.0.0.0]

jfry@J1# set interface fe-0/0/2

Junos – iBGP Route Reflector

Fryguy — Fri, 27 Dec 2013 13:05:04 +0000

Ok, time for some BGP Route Reflectors!

Now onto BGP Route-Reflectors. For this lab our IGP will be OSPF, our BGP will be done via the connected interfaces, J1 will be the RR, and we will advertise our loopbacks into BGP.

First though, reset the lab to the rescue config on J1, J2 and J3, and load the base on R4.

Ok, now to configure OSPF and BGP on R4:

R4#conf t

Enter configuration commands, one per line. End with CNTL/Z.

R4(config)#router ospf 123

R4(config-router)#no au

R4(config-router)#net 192.168.14.0 0.0.0.255 a 0

Junos – iBGP

Fryguy — Wed, 25 Dec 2013 13:05:44 +0000

Ok, time for some iBGP!

Ok, BGP time. First thing we need to do is rollback all configs to the base. You should be Ok with doing that now on your own, so I will skip documenting that again here. Again, all configs, J1 – J2 – J3 – J4, are all back at their base/rescue level.

Now we need to configure R4 with a static default route to J1 for this lab.

R4#conf t

Enter configuration commands, one per line. End with CNTL/Z.

R4(config)#ip route 0.0.0.0 0.0.0.0 192.168.14.1

R4(config)#^Z

Now we can configure a static route on J1 to R4 4.4.4.4/32

[edit]

jfry@J1# set routing-options static route 4.4.4.4/32 next-hop 192.168.14.4 install

[edit]

jfry@J1# commit and-quit

Junos – Multi-Protocol Lab — OSPF and RIP

Fryguy — Mon, 23 Dec 2013 13:05:32 +0000

Time for some multi-protocol labs!

Ok, we have done RIP and we have done OSPF. Now time to put them together!

For this lab the Juniper devices will be in OSPF Area 0 and the Cisco device will be in RIP. J1 will sit in both RIP and OSPF and handle the redistribution between the protocols.

First up, we need to restore R4 config to our base and remove fe-0/0/7 from Area 1 on J1.

R4:

R4#configure replace flash:base.txt

And J1:

[edit]

jfry@J1# delete protocols ospf area 1 nssa

[edit]

jfry@J1# delete protocols ospf area 1 interface fe-0/0/7

[edit]

jfry@J1# commit and-quit

Ok, that is done. Time to configure RIP on R4 and J1.
