My first own network topology design
I took me a while to decide and start with my first own network design. How i started? Without a plan. Is this something good? I really don’t know. Am i happy with „what i have done until now“? I am, indeed. I’m just comparing my knowledge „me 3+ years ago“ reading 20+ question from…

Flashback: ISIS at home – SA520w “EOL”
Some weeks ago i spoke with one of my Mentors. I told him that i plan to remove my Cisco SA520W behind my HFC Modem because of no-possibility to use console and more than RIP as routing protocol on it. I started with “ip / subnet / vlans / OSPF or BGP” and he asked…

J2350 Upgrade from 11.4R7 to 12.1X44-D40
Since i’m enjoying my week-off i don’t have any reason not to do it. Since it should be straight forward i took a look on J-Web – looked simple – but did not worked. I was trying to get the upgrade done almost three hours but nothing changed. Back to cli and let’s see how…

Here is the output: root@ug-odb-pf-srx1> show configuration protocols isis export [ connected isis2lan ]; reference-bandwidth 1g; level 2 wide-metrics-only; interface ge-0/0/6.0…

Policy Based Routing…
This is something i really wanna know more about and how will i learn more? I will write about. In this post i will try to explain: – What is Policy Based Routing? – How Policy Based Routing works? – Configure Policy-Based-Routing to get some “hands-on”… What happends in “normal routing” when a packet hits…

OSPF/RIP – mutual redistribution
I cannot learn theory without “hands-on”. This is something i read – and maybe forget 2min / 2days after that. The next scenario i will take a look on it will be the mutual redistribution from rip into OSPF but OSPF routes from R3 are unable to reach R2 (R2 -rip- R1 -ospf- R3). Possible…

TUN-5-RECURDOWN: Tunnelx in GRE IPSEC
Not so long ago i came across such a log msg. Since i never “dealed” before with GRE IP SEC and i have to do some “hands-on” to understand how it works, let us do it now (freestyle). VIRL powered up. I looked on the cisco web page and google for this logs and there…
