Hi guys,
I'm just started to study for my ccie lab test.
I'm studing on Netmasterclass DOiT.
it says in IPV6 topic:
configure site-local subnet 7B on R1,R2,R3. Use SLA number A for this part of the network.
DOiT says the address is FEC0:0:0:A::7B:"x"/125
I'm confused about subnet-id and SLA number.
I read on RFC 3513:
Site-Local addresses have the following format:
| 10 |
| bits | 54 bits | 64 bits |
+----------+-------------------------+----------------------------+
|1111111011| subnet ID | interface ID |
+----------+-------------------------+----------------------------+
Site-local addresses are designed to be used for addressing inside of
a site without the need for a global prefix. Although a subnet ID
may be up to 54-bits long, it is expected that globally-connected
sites will use the same subnet IDs for site-local and global
prefixes.
Routers must not forward any packets with site-local source or
destination addresses outside of the site.
It shows only subnet-id
So, wath is SLA number?
Why it doesn't show "7B" in the subnet-id field?
thanks
