I want to use C3900 (Ios 15.3(1)T) as DNS server.
I found it can serve SOA, NS, A, MX records. It generetes PTR records automatically too. But we have some CNAME records and TXT ones.
I can't find any way to emulate it. Maybe, somebody knows?
1. general config
ip dns server
ip domain-lookup
ip name-server 8.8.8.8
2. SOA
ip dns primary bsu.by soa ns.bsu.by dvorc@bsu.by 86400 3600 1209600 86400
3. NS
ip host bsu.by ns ns.bsu.by
4. A
ip host ns.bsu.by 217.21.43.2
5. CNAME
? #have to be: xxx.bsu.by CNAME xxx.gov.by
6. MX
ip host bsu.by mx 10 xwall.bsu.by
7. TXT
? # have to be TXT "spf -v bsu.by"
