Base / Day-0
Config · Networking
Day-zero configuration for Juniper routers and switches: hostname, root password, system services, NTP, DNS, syslog, SNMP, and management interface via JunOS set commands.
BGP
Config · Networking
eBGP and iBGP configuration for Juniper JunOS with route reflectors, peer groups, communities, import/export policies, and prefix-list filters.
Firewall Filter
Config · Network Security
Stateless packet filtering on JunOS: term-based filters, loopback protection for the routing engine, policers for rate limiting, and apply-path for dynamic prefix lists.
Hardening
Config · Cybersecurity
JunOS security hardening: SSH lockdown, AAA with RADIUS/TACACS+, management plane filter, login restrictions, unused service disablement, and firewall filter for loopback.
VPN IPSec
Config · Network Security
IKEv2 site-to-site IPSec VPN for Juniper SRX firewalls: IKE proposal/policy/gateway, IPSec proposal/policy/VPN, tunnel interface, and security zone/policy binding.
IS-IS
Config · Networking
IS-IS Level 1/2 routing with Segment Routing MPLS (SR-MPLS) and traffic-engineering extensions for Juniper MX/PTX routers. Includes SRGB configuration and prefix-SIDs.
MPLS L3VPN
Config · Networking
MPLS L3VPN configuration for Juniper MX routers: LDP or RSVP label distribution, VRF instances with PE-CE routing (BGP/OSPF/static), and VPNv4 route reflectors.
OSPF
Config · Networking
Multi-area OSPFv2 configuration for Juniper routers: areas, stub/NSSA, route summarization, authentication, and redistribution via JunOS set commands.
SNMP + Syslog
Config · Networking
SNMPv3 with authentication and privacy, SNMP client lists for source restriction, structured syslog to remote collectors, and NTP - the monitoring baseline for any JunOS device.
VLANs
Config · Networking
VLAN configuration with IRB (Integrated Routing and Bridging) interfaces, access/trunk switchports, and RSTP for Juniper EX series switches.
