Juniper Switching Labs

Learn to set up a Juniper VQFX environment, configuring routing engine and primary forwarding engine, management and interconnect interfaces, RAM and vCPU requirements, paravirtualized adapters, and reachability checks.

Set up a Juniper VMX router by installing the VM image, configuring RAM, vCPUs, ten paravirtualized adapters, and management and gigabit interfaces, then verify connectivity with IP addresses and ping.

Learn the basics of Juniper configuration, including setting the root password, configuring hostname, assigning an interface IP in the same subnet, and enabling ssh access for root on Juniper devices.

Create VLANs in a Junos environment, assign IDs 10 and 20, name them appropriately, commit the changes, and verify with show vlan.

Configure vlan 10 and vlan 20 on a Junos switch, map them to irb ten and irb twenty, and assign gateways for pc1 and pc2 to enable inter-vlan routing.

Configure Junos IRB to route between VLANs by creating VLANs, mapping them to IRB layer 3 interfaces, and assigning IP addresses on logical units.

Configure Junos LLDP to discover neighboring devices using a standard, vendor-agnostic link layer discovery protocol, enable on interfaces, and verify neighbors with show LLDP and show LLDP neighbors.

Configure inter-vlan routing on juniper by creating vlan ten and vlan twenty, configuring pcs as access ports, and using a trunk to the router with vlan tagging and two gateways.

Demonstrates Juniper inter vlan routing with router on a stick, configuring vlan tagging and logical units on an interface, using trunk and access ports, and verifying connectivity with pings.

Configure inter vlan routing with a bridge domain that enables layer two bridging and layer three routing via irb, connecting vlan ten and vlan twenty on a juniper router.

Configure Juniper DHCP server to dynamically assign IP addresses to clients via VLAN 10 and VLAN 20, using IRB gateways, DHCP attributes, and access ports, with binding verification.

Configure a juniper dhcp server on switch one and a dhcp client on switch two using vlan ten and an IRB gateway to dynamically assign addresses via the Dora process.

Configure IPv6 stateful DHCP with a Juniper switch by setting a DHCPv6 server pool, assigning a /64 prefix, enabling router advertisements, and testing client binding and routes.

Configure persistent Mac learning on Juniper switches to retain Mac addresses after reboots, enhancing security while setting up vlan ten and an IRB gateway.

DHCP snooping and a binding database powers IP source guard on Juniper switches, mapping MAC, IP, and VLAN to validate clients and drop spoofed or replayed traffic.

Configure the interface mac limit on a Juniper switch to cap dynamically learned mac addresses per port, preventing mac flooding and enforcing port security, with drop, log, or shutdown actions.

Bundling multiple physical links into a single aggregated Ethernet interface using LACP on Juniper, with VLAN ten and VLAN 20, IRB gateways, and trunking to enable cross-switch traffic.

Learn to configure Juniper layer 3 with an aggregated ethernet interface to bundle two links, enable LACP, assign IPv4 addresses on both ends, and verify connectivity.

Learn to configure a bridge domain with VLANs 10 and 20, IRB gateways, and an aggregated Ethernet interface to bundle links and enable layer 2/3 traffic between PCs.

Configure Juniper VRRP on master and backup routers, assign virtual IP 192.168.1.1, set master 192.168.1.2 and backup 192.168.1.3, enable accept data, and implement OSPF.

Configure Juniper VRRP tracking to elect a master and backup router, track an interface, and automatically promote the backup when the tracked link fails.

Configure Juniper VRRP authentication for master and backup routers, establish vpip 10.1, assign master 192.168.1.2 and backup 192.168.1.3, and enable simple key 123.

Explore how the rapid spanning tree protocol (RSTP) converges quickly and uses designated, root, and alternate ports, while configuring VLAN ten, bridge domains, and trunk links on Juniper devices.

Enable rapid spanning tree protocol to elect a root bridge, designate root and blocking ports, and enable loop protect on non-designated ports to prevent switching loops when BPDU vanish.

Learn how root protect (root guard) prevents rogue switches from becoming root bridge by blocking superior bpdu on the root bridge designated port, triggering a root inconsistent state.

Explore how BPDU protect works on Juniper switches, enabling protection on end-host ports to block BPDU from rogue devices and disable port, with two configuration methods for rapid spanning tree.

Explore how VLAN spanning tree protocol works on Juniper, creating separate spanning-tree instances per VLAN with IRB gateways and access ports, and using STP with Rapid Spanning Tree for optimization.

Learn how Mstp maps VLANs to multiple spanning tree instances on Juniper devices, including instance zero and up to 64 instances supporting 4094 VLANs, with slower convergence.

Learn how to configure the virtual router redundancy protocol between Juniper and Cisco, designating a master with the virtual IP 192.168.1.1 and a backup, and verify failover with inter-router connectivity.

configure inter-vlan routing between Juniper and Cisco by creating vlans 10 and 20, setting access and trunk ports, configuring subinterfaces or router-on-a-stick, and verifying connectivity with pings.

Configure a trunk between Cisco and Juniper VMX router, create vlan ten with an irb ten gateway, and enable a bridge domain on trunk interfaces for inter-vlan connectivity.

Demonstrates establishing a trunk between Cisco and a Juniper vQFX switch using vlan ten, with an access port for hosts and an IRB-based gateway.
